Momodora I-III
Momodora
Disclaimer: this game was made by one guy and was admittedly a Cave Story fan game.
That being said, this game is dog shit.
Random platforms placed everywhere like a beginner Super Mario Maker level, terrible enemy placement.
I know everyone talks about music and mechanics in games but level design is really important as well. Hated it, couldn't wait to be done.
Momodora II
Much better in every aspect, you have levels that flow together, lots of enemy placement that flows with the movement of the player. Along with a great soundtrack, and fun cameos, makes this a must play in my book.
Momodora III
The first entry to have a steam page. This one lets you pick Momo or Dora as your character. Each has their own specific dialogue, but over all not much different than Momodora II.
Curse Crackers: For Whom The Belle Toils
Hey, do you remember when 2D platformer design wasn't just make very precise jumps and put a bunch of spikes around it?
Colorgrave remembers and made a superb game with a lot of love and care put into it.
The movement is not only very smooth but actually a lot more complex than initially anticipated.
The movement revolves mostly around a little bell friend that follows you around. You can use him to bounce in any which way. But combine that with your main character's acrobatics and you can do some real crazy stuff.
The original 20 levels are not a whole lot to speak about, they are still well designed so if you have a handle of the mechanics you can just zoom right through them.
The real meat and potatoes is in finding all of the secrets and the 30 or so secret levels, which require you to understand these mechanics in order to proceed.
This little game has a lot more packing in it than it looks like from the outset, and I'm surprised it's not talked about more. 7/10 as far as difficulty. But I fucking loved it and spent a fair amount of time on it. (Like 11 hours)
So if you're in the market for some good ole fashioned 2d platformin, give this one a try.
