I've just got it and I love it! It's just the kind of games I love and a perfect example of what I would make if I could create a game.
It has some bugs that prevent it from working on some MSX machines, though (e.g. Sony HB-55P plus RAM expansion, Toshiba HX-20 and others).
Releasing a .ROM version would be very nice too for those that don't have a disk drive but do have a flashcart.
