In Attack Hole, you will control a quirky black hole moving around the hall. This black hole has the ability to swallow all kinds of weapons and bombs before the countdown timer ends. When the timer reaches 0, a giant enemy will appear. Everything you have swallowed now becomes the tool for you to fight against this invader.

Collecting more equipment will help your black hole increase in size and accumulate tremendous power. At first, the black hole is very small. You can only swallow tiny objects. However, it will grow in size quickly. Then you will be able to swallow much larger items.
