Thanks guys! Definitely agree with all the points you two mentioned. I have ideas for a couple features that I think should help on some of these points, especially with acquiring powerups and changing how health works a bit, might also help reinforce the role of the theme.
Spawning of enemies definitely has to be tweaked, and I think the boss you encountered in the bottom left has a weird bug I gotta dig into.
Thanks for playing! I'll let you guys know when a new build is up :)
