Good game! I got to wave 11 and I think at that point the amount of bullets can be a bit unfair since it is not easy to dodge all of them nor are you meant to I assume, but I really like the main mechanic. It is satisfying to look at all of the bullets swirling around the black hole and I love that it has multiple uses. The fact that you can heal by consuming enemies with it really makes you think about the right time to use it instead of just spamming it at all times. I think it would be better if there was some way to increase your damage for the later waves as dealing with a lot of enemies can take some time. With that said, it looks great, it's a good concept and most importantly it's pretty fun!
