this game is cool and all, but one failure, it's too glitchable, I was about to make a spaceship to beat the game, so I check the crafting recipe, then the game freezes.
Please fix that glitch, it's pretty annoying to start over after a lot of progress.
Maybe you could add some more enemies, some stronger than the cat warriors (e.g. Rock golem) and some weaker (e.g. skeleton warrior).
maybe even some allies (mobs who help you) or stronger weapons, maybe you could even add ranged weapons or magic spells.
