Cool! I see lots of character here, and I really appreciate that you've alotted time to creating the cool visual setting to this game. Where your short production time might make it hard to write a fleshed out story you're instead telling it through the striking artworks and small details placed around the map. This world feels interesting for sure, and I'm intrigued to learn more about it.
A tutorial that is short, simple and to the point would do you good. I read that there's supposed to be a dash, and I sure didn't find it! I also found a pentagram that I thought that I could interact with, but I wasn't able to. Try to make sure that a player don't miss out on the features you've put your time and care in!
The game was fun whenever I had lots of enemies to shoot at, I honestly wish there was more of them!
Good job!
