Hey Mananuk,
I think it was better before. No huge problems, I probably just stumbled across a glitch. But this last version seems to have trouble with the controls, and after closing the program, I couldn't find it again! (I don't know where it is on my computer... it's not in downloads. It may've deleted itself.)
I would switch it back to the non-Fuse version. I'm not used to ZX Spectrum games, so likely most others won't have the same problem, just me. If you have a list of buttons to use to operate the Windows version, I can continue to debug it.
