I would have completed the game
but basically the game glitched after I maxed out almost everything.
Graphics are weak (inconsistent styles), but I like the rogue-liteness of the game, although I think it's much better when you (if you are a great player) can complete the game without any upgrades (like "Rogue Legacy" is super hard, but possible without upgrades), in this game it's clearly impossible.
I didn't immediately understood the ability to get some resources, but only if you have room for that - sometimes it worked, sometimes I got damage. As it turns out (it didn't take long), things on the right correspond to what you can and what you already do carry.
