Wow, this is amazing. This is the closest I've ever felt to playing MMX, even when considering the MMX "clones", like 20XX/30XX. And this is no clone! MMX was probably the game I played the most of as a child, and inspired my first game (Frauki's Adventure!). But this game is significantly better than that, so well done. There are a couple things I think could be improved, and a couple random ideas.
- The font in the dialog boxes is really bad. It looks ugly and is hard to read. You can get 10x better fonts for pennies, or for free.
- The camera could be improved. The game is at 240x190 or whatever base resolution, but that doesn't mean the camera should be moving in that space. The camera should be moving in the full unscaled resolution. That will reduce the jitteriness of the game a lot. Also, the camera could stand to be tweened to the player, instead of perfectly locked on. It just makes the game a lot easier for your eyes to track things, and makes it look more professional. Of course, you first need to get the camera moving in unscaled space, or the movement will look blocky and strange.
- The difficulty of the first boss is too high, in my opinion. I was loving the difficulty up until that point, at which time it seemed to jump. I loved the challenge of MMX games, and will always remember the first time I beat Chill Penguin. But the difficulty jumps too much too quickly at the first boss, in my opinion.
- In my game, I made it so that if you attacked while jumping, you would attack somewhat above yourself, instead of just in front. I think that could be really beneficial here, because you have aspects that cause you to float while attacking. Jumping up into an enemy and missing an attack off to the side doesn't feel great.
I think this game has massive potential. It's really cool and with some work it could do well. At minimum, you should get a Steam page ready to go. I'd also look for publishers, if you want to go that route. Contact me if you want me to put you in touch with some people.
