Stunning graphics! Wow. In terms of game play... I found the yo-yo mechanism counterintuitive because the character stops in mid air when the yo-yo is deployed. Also, this seems to borrow a bit from Super Mario 3 in terms of platforms, slopes, cannon ball projectiles -- but sliding down a slope into an enemy and jumping on a ball both killed me (was unexpected based on Mario play). And then in terms of polish... everything looks so professional -- except the "Mouse Go Roll!" banner on the main menu could use some love. But that is extreme nit picking. This is overall an amazing entry. Congrats!
