This is a crappy emulation version. Keyboard is locked to up-down-left-right-zxas-space-enter Speed is incorrect since modern PC is to fast to run emulator, and we have no way to modify ini files to reduce the game speed (typically 2x speed or 2.5x speed, which renders unplayable) I'd rather run the rom with a MAME emulator which you can define your own key layout and change the emulation speed back to normal arcade 12MHz either stick with MAME version or steam version, skip this one.
