Interactable items clipped into walls causing them to be non-interactable, enemy waves being stuck in a wander-and-lookaround stance and the audio bugging repeatedly everytime you do anything, some stuff that could be easily addressed if you intend to update your game.
Also, I did enjoyed the game once I figured out that I can build walls and get equipments.
It did took me a while just to know that “E” means interact though :)
