Thank you! This is all very valid and true feedback lol.
1.) Duplicator can be killed by shooting the Arm that spawns enemies, health bars are coming as well as dmg feedback, just ran out of time for the jam :,c
2.) The Sword difficulty curve is another casualty of compressed narrative for time's sake, the sword isn't supposed to be a good weapon until you've upgraded your melee and shield stats at the work bench, but I wanted to lengthen the early quests to not just be "go to boss right away, okay you're done now" lol. I'll work on a way to balance it better in early game :)
3.)"Glitch thing in the cubes" I'd love to fix, but I'm not sure quite what you mean. The darker floor tiles or the blue parallax layer? I think it may be something to do with how the engine is updating frames bcz they're not animated at all lol.
4.) The level up bench i'm 100% sure DOES work, did you have the right amount of scrap listed for the price? scrap not credit. This could also be another issue to do with the bad font choice lmao.
