Oh okay, that, makes sense then. I noticed that there was either regen or shield that reduces incoming damage upgrade, is it the same bug?
Yeah! Kind of sad, because there were some upgrades, that were a bit more interesting, and you can't use them, because of the bug.
It's okay I will check on it after the voting ends, if you are planning on releasing a patch. Also I might suggest setting limits for some upgrades, because regen makes you practically invincible at high levels.
Thanks! There will definitely be an update after the jam.
