Theirs this house with a rainbow looking texture the just feels really empty, i thought adding a chest like in the wawsp nest could help make it feel more rewarding for finding one. Also i noticed rally high level enemies spawn strange, like gators spawning with their jaws locked inside of each other, and some rocks and cuddle bugs spawn under ground. Finally i recommend increasing the item drop rate for special enemies and for higher level enemies, the only areas i get any items is really close to the main structures like the squatting humanoid and graveyard.
btw i love this game a lot and really enjoy the ideas of Juice Galaxy and hope to see more of it in the future.
