This game is really fun! I got it two days ago and can't stop playing it. I also can't get passed stage 18. You should include some instructions inside the game. This is great and thanks for writing it! Great job!
Thanks for the kind words. Credit goes to Sanchez Crew for the ZX Spectrum Next creation and also Battle City for the old school version. Same when I played it and though it might be nice to share it with some that don't have access to a ZX Next.
