I'm giving it a reluctant upvote mainly because I'm a sucker for looper games and I like parts of what's going on here. I don't like voting for potential, but I'm kinda voting for it's potential.

It's simple as described, but it comes from a lineage of games that are fairly complex. I really like the idea of earning a meta currency for upgrades between loops, that's what I consider the strongest part of the game right now. The interface is simple, that's a good place to have simplicity.

But I'd like more depths to the dungeons, to the pathing, to the strategy, to the purchases. All the purchases are just basic +% to a thing, nothing really changes the game's mechanics or how you interact with the game, it's just numbers go up.

Mid and late game unlocks that give you more opportunities in the lower levels would be cool. (Like unlocking the ability to overlap yourself once so you have more pathing opportunities.)

You have two tiers of upgrades and both are just numbers go up. Maybe make that equipment shop basic numbers go up and that second tier of shop more interesting things.
