I like the game. it is fun.
Edit: I have now beaten the game. It was fun methinks. At the end of the first floor, I was forced to pick a relic that dramatically changed how I played the game. This is a great moment and there is a lot of potential in this mechanic. I ended up picking the relic that made it so I only gained energy while standing still or from killing enemies. The game got really easy after that, the scaling felt a little off, I was gaining energy faster than I could use it!
Regardless, cool game, very fun, two thumbs up!!!
