I really like this! How many bosses are there? I gave up on the lava wyrm, because the platforms are really punishing! Every platform in this game looks like they can be pass-through objects. So I guess we don't have to emulate every retro thing, especially the controls. Player could use some air control for precise landings and or attacks. So that way, when player makes a mistake, they blame themselves. Also a pause menu could be helpful, I died sometimes when something distracts me from the game. But other than that, I think this game is really special; bosses and stages work in tandem to make the fight more interesting and I love the nostalgic feel + easy to understand gameplay. This feels like a hidden gem that I'm glad I got to experience. Great work!
