I can totally see your critique about using well-known characters. The urge to homage those classics was just too strong this time. I didn't copy them 1:1, but redrawn and adapted them to make them more my own version. Actually, there was also a Bubble Bobble biome, but I removed it for the release, because it was too much a copy. (Hint: Use the cheat mode to have access to it)
Nice to hear my game triggered a few memories. Was also fun to create it =)
Thanks for commenting and playing!
