I think you should have a powerup that lets you smash through walls n stuff
should obviously be pretty rare
or maybe it could be at a kind of shop place like the ones in spelunkey
I tested this out with the bomb, it was pretty fun but kind of game breaking. It's definitely something to think about though.
I added simple prefab loading to the dungeon to break up the combat a bit.






I'm still not sure how to handle the half cube things, since jumping is still in the game you can jump clean over them but that makes things too easy.
Right now you can throw things over them, and shoot over them.
I'm going to also add support for bottomless pits and fire pits, but I'm not sure how to balance those out yet. As I don't think a one hit kill would be fun.
Edit: just noticed that I need to do some cleaning up of the seams here, you can see some parts you shouldn't be seeing lol.
