also something to note is that's really interesting someone implementing a mechanic where enemies or monsters can latch or cling onto the character, especially with the belly movement it's really nice, what i would like is as other said to implements other oponents in the dungeons, you can also implement other monsters that can latch onto like slime or other things, plenty of games don't have this and few have this feature, so it would be really great to developp a little bit more this part!
also great work!
