Brilliant
Amazing innotive concept, loved it.
The game can be broken near the end if after the area you have to jump up, if you jump up to the room above (the same room you fell down into that room to) and in midair change the tile below you to the new one, you get stuck.
and TheKekeMaster, clearly you decided to give it '0' and said its broken, before going right a bit more hmm? timer doesn't start straight away.
