Thanks, I'm glad you enjoyed it!
Currently implementing some stuff wrt difficulty. Hopefully will be slightly smoother. I've been wanting to add more melee combos for a while, not sure if I'll do a wall jump or a dash but those are both interesting ideas!
Debug mode has been requested enough that I am probably doing it. I think I'd like to get everything implemented in normal gameplay first, though. Energy is probably going to remain capped at 100%, but I can confirm that I'm adding a bigger max size.
I have no idea how long it will take, unfortunately, but I'm just putting the finishing touches on the new features I wanted to add. Next step is actually making the level, which might take a while. A ton of stuff has happened in my life during this dev cycle, so I haven't been able to work on it as consistently. It would be awesome if I could get this out before the end of the year.
