Thank for the feedback, glad you enjoyed it.
I really like the idea of doing something like Hotline Miami since that was my main inspiration, but a wave shooter seems simpler for a first project and I'm trying to limit my scope to a pretty small game for now. In the future I'd definitely want to do something like that.
Beyond 2 extra stages and a secret or 2 I don't have much more content planned. I'd like to but I'm more interested in finishing this project and cutting my teeth on something new. Maybe I'll come back to it eventually and turn it into the gorillion hour ARPG it was truly born to be.
