Thank you so much!! The RH/LH accessibility came after having my southpaw bf playtest and I noticed him struggling with the controls. Initially I was going to have manual key bindings but that felt like more work for me (and onboarding friction for the player) so I opted for a simple toggle. Happy to hear it found its way to someone's future game :)
I should have cut wave #2 or 3; after playing more, the easy waves did feel a beat too long before the intro of the tougher printer mobs... so many learnings came out of this jam!
