very clearly incomplete. Settings button says “click here first” but then the settings page itself is blank. Clicking play button just gives me a gray screen. So if there's no settings, why do you have to click it? What is it doing? After that, tried to play level 1 - was unable to complete first jump of first level, character just barely would not jump high enough. Screen auto-scrolled past me, but level kept going even though I was “dead”.
I don't want to be discouraging, but this definitely needs some more polish.
