Ok. First things first- I saw your game o discord a while ago, and once I read the title I figured I need to do better with mine. So the title of the game you see below this post is partially your fault!
Now- for the game itself. It's pretty great. The color palette, sfx and music all work together and go for super retro look. The controls are tight, so that's good. Compared to other entries the difficulty is on the easier side, but that's good for me, as I am known not to finish games that kick my ass repeatedly.
The boss design is where your game shines the most. I like their look, liked their patterns, and that's probably the most important in the boss rush game, right?
Overall- one of the most polished games on this jam!
