I will start with saying, I think this was the only entry so far (that I saw) that had perfect 5/5 accessibility options with the keybindings. Good job. You paid attention to having a proper menu, and everything, felt very polished.
The only issue was the bug where enemies don't attack. By the way, it would be ool if some enemies would not shoot but would try to push you in the black hole.
I also loved the minimalistic music. Great job, will follow you in case you fix that bug. :)
