Thank you very much for feedback :-)
No, I'm sorry. I'm trying to build a game for the SNES DEV Jam at the moment (a little childhood dream). But I try to work on the GB-Game next months. Maybe I will release a demo till the end of the year (I only can work on it at evening).
Reading that you're so ineressted in this project makes me very happy. At the moment I have to enhance my developement skills, but I hang in there. I'm looking forward to play your game(s) too. Thank you again.
