Very addictive, I played for about an hour and a half! I think there's some balance issues, as it's pretty difficult but it's a game jam prototype, that's pretty normal.
I tried to bully the game a bit by going fast, clicking around etc... Only bug that arrived was that I ended up getting the "you farkled" once when I had actually won. That's the only glitch I managed to force though, and I couldn't make it happen again, so, well done!
