The gameplay is very simple. You control a black hole tied to your mouse cursor and move it around the play area to absorb animals. The process is not instant, so you need to keep the black hole over an animal for a second or two until it gets pulled in. Each run has a very short time limit, and your goal is to consume as many animals as you can before time runs out.
The real fun comes from the upgrades you earn after each run. Every animal you devour gives you a dollar that can be spent in a straightforward upgrade tree. You start in the center with four branches that improve the time limit, the number of animals, the sucking speed, and the pull force. Buying an upgrade reveals new ones further along the branch. Available upgrades are easy to spot since they have a yellow outline and gently pulse.
You never know exactly what will appear next on a branch, and some upgrades only unlock after you purchase two separate upgrades that converge on the same node. Each upgrade can only be bought once, though some appear multiple times along a branch with stronger effects. For example, the first pull strength upgrade increases it by twenty five percent, while the next raises it to fifty percent. As expected, stronger upgrades cost more.
The starting area is a farm filled with chickens that spawn from marked zones. At first, only one section of the farm is available, but as you complete runs and devour more chickens, additional areas unlock. Once you consume enough chickens across multiple runs to fill a progress bar, you move on to the next farm and a new animal type such as pigs or sheep. Unfortunately, the farm environment itself never changes.
While the final stage is quite grindy and lasts almost as long as all the previous stages combined, the overall experience is still fairly short. The game starts slowly, with only a handful of animals per run, but eventually you grow powerful enough to absorb hundreds or even thousands. You also unlock helpful abilities like lasers that randomly consume animals or a pulse that pulls them closer to you.
After finishing the campaign, you unlock an endless mode with light roguelite elements. There is also an idler mode planned, though it is not available yet. In endless mode, the objective is to consume a required number of animals before time runs out. If you succeed, you spin a wheel that offers three random upgrades, from which you can choose only one. These upgrades are the same as those in the campaign. Each stage increases the required number of animals, but there is no reward for exceeding that goal.
The mode starts off well but quickly falls apart after a few runs when the play area becomes much larger. If you do not pick the right upgrades, especially movement speed and extra time, it becomes nearly impossible to gather enough animals to advance, which means there’s no balance and the choice of upgrades is only imaginary. Even with the right upgrades, the low number of spawned animals becomes a problem. While you deal with one group, others scatter across the map, forcing you to chase down individual animals one by one, and fail.
In conclusion, this is a fun and straightforward upgrade based game that works well for a couple of hours. However, once you finish the campaign, there is little reason to keep playing, as the additional mode does not offer a balanced experience.
