This is an addictive game. At first I thought it escalated too quickly. After playing it half a dozen times, I changed my mind. It was nice that I was able to rapidly get back up to speed.
A few things to note. Some juice would make a world of difference in this game. If you're unfamiliar, check out Mark's video on the subject. Also, the music was repetitive so it got old fast. It's not bad music, just tiring on the ears after a dozen playthroughs.
Overall though, I enjoyed this game a lot more than I thought I would at first glance. Nice work!
