Excelent visuals and really intuitive. Also, great choice of music :)
My only issue with it is holding the CTRL key and the arrows simultaneously, which makes my mac wanna shift windows. I have to re-test it on another OS later.
thanks :-) and sorry for this Mac issue (that I didn't foresee). It happens also in fullscreen mode (you activate/deactivate it pressing F2)
no worries!!! Tomorrow I'll play it again on a PC and all should be well ;)
