Great concept, but having "this tooltip left intentionally blank" appear on everything is a huge turnoff. It feels unfinished. Half the text is gibberish too. Reading what a perk does is the most unhelpful thing of all time. "Flip all non-enemies" what does that mean? You never even told me what an enemy is. How does it trigger? When does it trigger? I bought it and nothing seemed different in my next round? Nothing "flipped". You need to work on your english and UI. Having a perk written out like "flip* >flip>flip * group" means NOTHING if you don't explain wtf "*" represents, or what a "group" is. You gotta playtest man.
