It was good! I liked when it got fast, and having to react quickly was nice. I will say, when I played it at least I couldn't use the ability - my best guess is I had to buy it from the shop first, but I didn't have enough money to get anything after my first run. The other thing was a run felt pretty long- maybe compressing it down would help hold player's attention for longer? I liked it, even with those quibbles though!
