I'm surprised you could make some pretty challenging levels with such simple mechanics.
Thorns are annoying but you could exploit them as walls with a pain state, but the glass gave me A LOT of trouble. Kinda gave up trying to fully complete the last level after some time. I get the idea why the bee does not turn when it hits the glass, but yeah, I have no idea how to beat it - maybe you need some very precise angling?
Anyway, it's a really cool game. The bee is very cute and the ending animation made me laugh, especially when the bee gets the honey all over its face.
Good stuff!
