Hi, i'm the developper of Lock'n chase. For the moment the dev process goes well. I've just finished coding a PSG librarie to make some sound effect and a little music. The only problem is that i'm not musician
So i have the same problem on Coleco or on any console with a music chip ... But, i'll try to do something acceptable.
I'm waiting for the maze graphics from Crapahute, the game engine is near finished, just adding score, extra life tuning, welcome screen, next level screen, game over screen, but it's details.
I think i'll add one or two more maze for this PCEngine version, well, i'll see.
Thanks for your comments and appreciation. (And sorry for my bad english, i'm french).
