That third level .... I thought the game was broken lol. Had to look through the feedback and saw you'd said it was on purpose, so gave it another go!
Bit of a risk with using a glitch like that for a level as some people (myself included) will naturally assume it's a game bug so therefore - the game is borked. I would have stopped there if I hadn't seen the feedback saying it's actually meant to do that.
Cool game though, the fact you can just zoom off the end of the line scared me a few times but it didn't make me fail so, it was alright in the end :D One of the better puzzle games I have played so far!
