Woops, almost forgot to comment !
I played the whole game while streaming to a friend, who happens to love bonsais and he was absolutely amazed by the concept.
The puzzle works, the levels are greatly designed, the music fits very well and is beautiful on its own : it's a superb submission of course, but it is a great game first.
The only problem I had personnaly, but that's just because I suck at puzzle games, is that I took a lot of information at once, but let's not forget it has been made in 2 weeks and you didnt have time to make three levels per tutorial step to give us time.
No, really, you nailed it, congratulations.
