I've been able to reproduce the menu bug described in BallDor's review. This happens when the player quickly cancels just after entering the rift, before the graphical transition is finished. Probably a variable that is changed after the transition instead of being changed before. It's possible to come back to normal by using the exact same method, it seems (just in case someone else have this issue)
Apart from this issue, this game is cool, with an interesting concept. I'm not really fond of the sound, music and graphics though.
