Repetitive item-collecting and zombie-fighting loop where success requires speed and luck, but failure offers nothing in return.
Once you’ve chosen a character—this selection is purely cosmetic since there are no stat boosts, abilities, or special perks—you’ll be sent off on your very first run. The game requires you to clear the “easy” mode first before the other three difficulty levels become available. Fortunately, the introductory challenge isn’t overwhelming and works mostly as a tutorial to ease you into the loop.
Each run follows the same structure. Your task is to move through a series of shops and gather all the items listed on your shopping list before the countdown expires. If you fail to collect everything in time, the run ends abruptly, and you’ll walk away with absolutely nothing. There are no partial rewards or consolation prizes for failed attempts. Increasing the difficulty doesn’t change the core loop, but it does raise the stakes by throwing in more enemies, requiring a greater number of items, and intensifying the boss battles waiting at the end.
At the start, your offensive capabilities are limited to a simple punch. Eventually, you gain access to a firearm, which sounds promising at first but comes with a major drawback: ammunition is limited and persists across all future runs. In other words, if you blow through your bullets too quickly, you may find yourself completely unarmed later. On the other hand, the gun isn’t particularly powerful, so relying on it heavily rarely pays off.
Item collection itself is handled in a straightforward arcade-like fashion. Each store consists of a single screen where your character moves side to side as items fall randomly from above. Sides of the screen loop, which means you can exit one side and show up on the other.
While each shop has its own unique pool of items, you aren’t restricted to grabbing only what’s on the list. Anything you pick up contributes to your final payout at the end of the run. However, you cannot proceed to the next store until you’ve secured every required item. Since drops are random, sometimes you’ll get what you need immediately, while other times you’ll be left waiting anxiously.
This can be risky because the timer is shared across all shops, meaning dawdling too long in one location can jeopardize the entire run. On the flip side, if you’re already in the final store with every list item collected, you can milk the clock to snatch as many bonus items as possible.
Of course, you won’t be shopping in peace. Zombies frequently fall alongside the items, and others shuffle in from the sides of the screen. These enemies can be dealt with using your basic attacks, but they’re constant interruptions. Once you’ve completed all the stores, the run culminates in a boss fight. While the fight is also bound by the timer, the game does give you a reset, so the clock doesn’t carry over from the store segments.
What makes this cycle frustrating is the lack of rewards for failure. Runs can end abruptly with only three hits from enemies, and bosses in particular dish out damage quickly. Although health packs and ammo drops exist during store sections, they’re extremely rare.
Power-ups offer some relief, but only temporarily. At the in-game shop, you can purchase consumables such as extra ammo, health refills, magnets that draw items toward you, protective shields, or bombs that wipe out every enemy on screen. The drawback is that each power-up is single-use. Permanent upgrades, like stronger guns, exist but are very expensive.
Ultimately, the game shows its full hand almost immediately. Beyond the first run, everything else is a matter of grinding toward achievements across hundreds of runs.
