About the game
You are a lab mouse on the run through the Dutch countryside. Dodge or shoot traps, snakes, cats and owls, then face the scientist who wants his test subject back. Scoop up cheese as you run, spend it in the shop between levels and grab power-ups off the road when the chase tightens.
Real 3D world
A third-person chase camera is the default; press V for the first-person view. The camera reacts to your moves, the scenery scrolls in parallax, and every enemy behaves in its own way: snakes switch lanes, cats jump, owls dive from above.
AMMO risk loop
Every shot spends one AMMO. Traps and enemies give it back in different amounts, so each shot is a bet: is it worth the spend? Weigh cheese points, upgrades between levels and the risk of running dry.
Play anywhere
Keyboard on desktop, touch controls on phones, including a left-handed mirror of the interface. The game runs in the browser and can be installed as a Progressive Web App, so it works full-screen from your home screen.
Game modes
There are two caliber modes, NORMAL and EXPERT. You pick one on the main menu before you start. There is no separate difficulty switch: the game gets harder by itself through twelve levels (see Levels below). Every run starts with 5 lives.
| NORMAL | EXPERT | |
|---|---|---|
| Starting AMMO | 100 | 50 |
| Snake / Cat / Owl health | 2 / 3 / 4 hits | 1 / 2 / 3 hits |
| Boss health on level 1 | 20, then +5 per level | 15, then +4 per level |
| Speed | Standard | Faster on every level |
The goal of a level
Run down the road and collect seven letters: C, H, E, E, S, E and a cheese wheel that stands for the last O. When the word is complete, the scientist boss comes out as soon as the road ahead is clear. Beat him, fly through the portal that appears, shop for the next level and keep going. After level 12 you win.

AMMO, shooting and lives
- Every shot spends 1 AMMO. A shot hits only a target in its own lane.
- Hits give AMMO back: every destroyed trap or enemy returns some (see the table below).
- When your AMMO reaches 0 and none of your shots is still in flight, the run is over (GAME OVER).
- You have 5 lives. A hit takes one life and gives you 2 seconds of invincibility. With no lives left you can restart the level.
Enemies
| Enemy | Health | AMMO reward | How it behaves |
|---|---|---|---|
| Mousetrap | 1 | 1 | Sits still on the road, one to three at a time in different lanes. |
| Snake | 2 (Expert 1) | 3 | Switches to a neighbouring lane about once a second. |
| Cat | 3 (Expert 2) | 4 | Cuts across the road diagonally, then jumps into the lane where you stand. |
| Owl | 4 (Expert 3) | 6 | Flies high, then dives at you up to three times. While it is high your shots pass under it. |
| Scientist (boss) | 20 + 5 per level (Expert 15 + 4) | His health + 5 / 6 / 7 | Throws syringes, steps between lanes and charges across 1 to 3 lanes. |
A cat shows up after every two snakes you destroy, and an owl after every cat. There is never more than one cat or owl on the road at once.
The scientist
He stands in one lane and throws syringes down it, then steps aside or charges. A red zone on the road warns you where the charge will hit: one lane on three-lane levels, up to three lanes on five-lane levels. The more damage he takes, the faster he attacks. A syringe has 1 health and gives back 1 AMMO when you shoot it. The boss reward is his health plus a bonus: +5 on levels 1 to 3, +6 on levels 4 to 7, +7 on levels 8 to 12.
Collecting cheese
Cheese lies on the road, often on top of a mousetrap, and some pieces float high, so you have to jump for them. Every piece gives cheese points: 3 on levels 1 to 3, 4 on levels 4 to 7 and 5 on levels 8 to 12. Cheese points are what you spend in the shop.
Collecting letters
Letters are amber and drift toward you slower than the road. A new letter appears only when two conditions are met: you have run a certain distance since the previous one (longer on higher levels), and you have fired at least 5 shots since you collected the last letter (10 shots before the final O). If you miss a letter, the shots you have already fired still count, so the next one needs no extra shooting. The cheese wheel O appears last, only after C, H, E, E, S and E are in your pocket. Every letter you collect makes the run a little faster.
Levels
Twelve levels in three groups. Speed rises from level to level and with every letter, and the road gets wider with more lanes, which means more things to dodge.
| Levels | Lanes | Cheese piece | Boss reward bonus |
|---|---|---|---|
| 1 to 3 | 3 | 3 points | +5 |
| 4 to 7 | 4 | 4 points | +6 |
| 8 to 12 | 5 | 5 points | +7 |
Power-ups on the road
- Fireballs – double shots for one AMMO. Five charges appear on the road after you earn another 50 points of rewards.
- Speed – +50% speed for 5 seconds.
- Slow – -50% speed for 5 seconds.
- Heal – restores 1 life. It appears on the road when you are down to your last life.
Shop and backpack
A shop opens before every level, the first one included. Items you get go to the backpack and you use them during a run.
| Item | You spend | What it does |
|---|---|---|
| Heal Potion | 50 cheese | Gives one life back. |
| Time Warp | 100 cheese | Slows the run to a calmer pace for 20 seconds. |
| Enemy Rush | 150 cheese | Sends a snake, a cat and an owl one after another, so you can earn AMMO. |
| Cheese Magic | 10 AMMO | For 15 seconds traps, snakes, cats and owls turn into cheese you can just collect. |
| Extra Life | 20 AMMO | One more life and one more heart for good. |
| Fireballs | 30 AMMO | 20 double shots. |
| Get Ammo | 500 cheese | Exchange for 25 AMMO. |
| Get Points | 5 AMMO | Exchange for 50 cheese. |
When you spend AMMO, the shop keeps a reserve for you: you must have at least 20 AMMO left, or as many as the next boss has health.
After the boss
- The boss drops a reward that flies to you: a heart (one more life and one more heart for good) if you lost no life in this attempt, or a Heal Potion otherwise (a life back if you are hurt, otherwise it goes to your backpack).
- With no lives left you see the LOST window and can restart the same level with 5 lives and an empty backpack.
- When your AMMO runs out, the run ends with GAME OVER.
- After level 12 comes the victory screen. Your AMMO carries over to the menu, and the ALL TIME screen keeps your totals: cheese, shots and kills.
