This was fun once I figured out some of the nuances of gameplay. I kept getting beaten' by the flying cubes because all of a sudden they turn orange and attack rapidly and become immune to any sprays (found that yellow bucket helps to deal with them though). It currently has a slight lack of responsiveness to being grabbed and used, and I'm not quite sure what causes the buckets to sometimes auto use when combining them. Maybe include a bit of a guide for how to handle certain enemies since maybe there was something else going on that gave enemies immunity to my attacks sometimes. I think I managed to survive to wave 14 as my best run. It's cool how blue bucket = shield, red = heal, and yellow = "thorns", but it's slightly annoying when I get a bunch of buckets and blue colors tbh :/
I hope to see it developed more, colorful job!
