Hey, nice game you created! :)
I get the idea with wrong keys but I fear you will be turning some people away with it before they get to play the game. It can be worsened because you used Z as an interaction key and didn't map it depending on the keyboard layout. On my german keyboard I had to use Y. QWERTZ/QWERTY layout issue. Don't know if that is intentional :D
I liked the camera work and the amount of hidden passages. Got a little bit frustrated with the two fireballs in the north. Is there anyway to get beyond there or is it just a trap that you can't escape? Managed to find the correct way after some time :D
I loved that ending cutscene. Huge fan ob DBZ
