Great take on the clicker genre! Very engaging. It progressed a little faster than it could have to keep the player 'working' for their upgrades all the way to the top, but it erred on the side of being a little too fast rather than being a slow crawl, which was nice. Some of the upgrades were not very clear about what they actually affected, and some of the upgrades with custom visuals to join the leaf roombas were very far into the game compared to the roombas, so I would consider adding thm earlier on to show off your work. All in all, great game and experience!
