If you could make a version for NTSC, I'm on board! In the meantime, I wish you well with your new release. It looks really good.
I'll be making a full version in the future (possibly disk but definitely a 512k cartridge), and that will have both PAL and NTSC support.
Fantastic! I'll be sure to keep a look-out for it!
Please, add hiscore table. An arcade shooter without hiscore, is not complete. :)
Anyway, Neutron is a great game!
