Good job. . .
This game is not impressive.
But. . . considering it is your first time, well done. A few pointers, hotkeys are good, but people like buttons too, so you should have both. For puzzle games, you usually want a walkthrough available. So keep at it and soon you be a great flash designer.
Thank you very much for playing and for your advice. =)
Buttons would have been useful, but I really didn't know where to place them. Working with Game Boy Color resolution didn't leave me with a lot of free space, although I really enjoyed the limits I had to wrestle with. =D
My only complaint is that you should have a BGM and a menu/setting/restart button.
The BGM is missing because I don't understand anything at all about music. =)
Regarding buttons, if you mean something like 'restart level' and 'get back to the main menu' you can respectively press 'R' and 'Q'. Thanks for playing and for your review! =)
