Hey!
First of all, the game is really neat and fun! :) Well done!
Can't wait for the full version. I want to play the hidden levels, hehe ^^
I found 2 small bugs, I think it's OK to mention them:
- the 'level complete' fanfare plays multiple times, every time you hit the collider of the flagpole
- in the ice level was a one up (heart) that I could not collect
Keep up the good work! :)
