What an awesome game! It's chaotic but very fun and the music makes it even more enjoyable.
I think Inner demon is completely OP after a few levels, it pretty much took care of all enemies so I didn't even have to focus on them.
Also the web version crashed every time I got to ~6000 points, with the message "Table index is out of bounds", so I had to use the Windows build, and now I have two highscores :/
Really good job!
