I have to say, this is the best GB indie game, ever. I'm playing it on Analogue Pocket and it surprised me. I wasn't expecting to have so much fun, detailed sprites and challenging (but not so hard) stages. In some parts reminded me of "Wonder Boy 3: The Dragons Trap". GREAT JOB
I purchased the rom, but I love it so much that I bought the Modretro cartridge.
I hope some day you make a "Wonder Boy 3: The Dragons Trap" style game for GB
