Works great on browser now. Enjoyed the game, I found that it was quite easy to cheese by simple going up to the top row of tree and spamming E whilst going right, so it wasn't hugely challenging, but I think that would be a easy fix. I think an animation to show when the tree had been picked would have been nice, and a little more variation in the shop animation. But otherwise great!
