on the level three its possible to access the map below, by (i believe its a bug) changing the world on the platform in between the spikes. I enjoyed it alot tho :D really like the mechanics and it works smooth. :) Loved it!
There are several secret passages in the game, it was probably one of them. Thanks for the feedback! I hope you didn't have time to play when I first uploaded the game, I accidentally forgot to remove the player's progress before the release :d
its just amazing, i loved every second of it, though i think i do be having skill issues because i got stuck for 30 minutes on the third level.... BUT thats on me, my friend finished it rather quickly :D
