Wow the idea is really cool and original!! Well done!!
This game, at least for me, suffers from a deph perception problem: I can't easily tell where i will land because the point that i think i'll spawn and the point that the actual spawning point are different. That, combined with the overall hard difficulty (only a bit hard btw, not too much), made me try even the simples room at least twice
I like the idea of having bonus collectables in your game, it's always appreciated!! Also the music was AWESOME, tell your friend that it did a very good job!! (If only i knew how to make music this good... :/)
