I think the most important thing would be a strong clarification regarding the controls. I still don’t fully understand how to use my abilities, so if the abilities are supposed to be used, it’d be nice to actually use them.
But as great as your game is, there is a lot of polish you’ll need to sort out. Things like certain keyboard characters not rendering properly, and bugs that caused me to get damaged by enemies despite having killed them. But again, it’s a game jam and your game has a lot of content for a one-person team, so still fairly fun.
