How do I use the white crystal on the shopkeeper?

Sweet idea! It's surprisingly playable for a maths game. Good work!

nice little adventure. all puzzles were logical and not too far fetched. the glass is hard to click though (not that you have to) ;)

Really cool game. Great combination of platform and defense. Graphics are great too. Nothing to complain about. Good work!
