Awesome audio-visual design... that gave me a total retro feel. That background sound just felt real with headphones and the screen was a bit to much bent, but it just looked like a very old tube ray monitor... nice! You totally hit the inversion topic and we were able to solve much of the game. But it seems there is a bug in it for the 4th item to collect. We actually had a look at the source to find the solution... but well we collected it but didn't have the flipxy option afterwards and also it seemed to have a bug when displaying the path there. Would have liked to see the end titles. Nevertheless, a great game with a lot of puzzle feel. You surely have spent a lot of time creating the level. Thanks for that awesome experience. Tell me if you have fixed the bug... then I'll try to finish it...
