i think i will be updating it yes, new grenade types, money, a grenade store where you have to unlock the things first in levels (like shovel knight) are already in the godot project, new types of hearts and a heart store are planned and level 5 has been entirely designed it's a matter of making it all, so at the very least a minor update is coming but if i do release something on steam i'll shoot for maybe 12 levels and like $5 for the whole thing
