Seems like a really cool idea for a roguelike. As it stands it's a little too hard for me though. The enemies do too much damage and there aren't really any good opportunities to heal. If you do some kind of post-jam patch that makes the enemies easier, maybe the harder path can also power them up? Like if you keep going to the right the enemies eventually end up as difficult as they are in the current version. Likewise, going left could heal the player more.
Good work making all the assets yourself, that's definitely something to be proud of!
