Solid idea, the black hole as a mechanic worked really well, it reminded me of the Black Hole Gun in Enter the Gungeon, and worked basically just like that! It makes enemy bullets sink into it, but also affects the trajectory of your own "bullets", so you really have to think where to put it! Controls were clear and worked well. I didn't like the fact that you can take dmg from your own spawns, I understand the idea behind it, but for me it was a bit much. Maybe it just takes some time to get used to, though :)
Overall, a very solid entry, good job!
We'd also appreciate big time if you had time to check out our submission! :)
