yeah! enter the dungeon was one of the inspirations for this game, so cool you caught that!
about the gun: it’s a bug. it actually also occurs when punching, but it’s less noticable since punching twice an enemy already makes him die, while with the gun you need to hit him four times to kill him. enemies have 20HP, but the bar is set to be out of 100HP rather than 20, that’s why at the first shot it drops till 15HP (gun deals 5HP of damage), and then to 10HP, 5, and 0, which makes it seem off. thanks for pointing that out! i’ll fix in an update.
also thx for talking about the difficulty! i was worried the game would be too difficult for some as people from playtesting couldn’t beat the 2nd in like 10 tries, but I see it has been resolved :-).
