Cool little game! It took me a while to understand the dash, so I got stuck in level 2 for ages ^^'. All the text blocks in the beginning are really intimidating, and it's easy to forget something ^^'. I think it would have been better to slowly introduce mechanics accross several levels rather that explaining it all in one go. Like don't mention the dash in level 1, but explain it in level 2, where it's truly needed ^^'.
Otherwaise, I liked the idea, good job =)
