Oh man what a great game! The combination works and I had a lot more fun that I initialy expected. The track difficulty was ramping up quite steep and it took me a bunch of attempts to get the last track.
Presentation is fitting and i like the style. The music is helping a lot to get into the flow state.
Only other complain would be, that at the end i only rolled over the upgrades and did not try to complete the last track on a better time, because it was not worth it anymore.
Awesome game, good job! (Finished in 33min)
