Really fun, captivating and even addictive!
The only major issue for me was the lack of info - most of the time I didn't quite understand what's going on. What is a compo? How is money calculated? What do the bosses do? What do powerups do? Also, it would be nice to have an option to see your current garage. After a few playthroughs, I kinda deduced some of the answers, but it would be much better if I had them in an explicit way :)
