I'd say this felt very much like Mega Man, but I actually beat it so that can't be right x3
Had an absolute blast with this one.
Makes me feel like the whole jam was created just because you really wanted to make this game and didn't want to wait to do so, that's how much passion is on display here.
The gameplay is an absolute joy all the way through, very responsive, enemy and platform placement is a bit too friendly for it to feel like classic Mega Man, but I'm not complaining one bit.
The tiles are also very well done, with a lot of care to replicate the kind of style those games had.
Also points for the little arrows in the rightmost stage platforms, good pointer for navigating the player without being too in-your-face about it.
Enemies are well sprited and look distinctive with good variety, and the player movement is very fluid and responsive.
Powerup system is cool, I like how if you pick up a third you can use your powers to swap the orb around to your preferred combo. Mine was Yellow+Red, very handy.
Music was stellar and kept the momentum going all the way through.
I don't have any critiques really for this one, I just wanted it to be longer.
You could honestly take the quality of what's here already, make more of it and publish it imo. It's that solid.
