Just binged through a bunch of games recently, quick impressions:
Cloudbuilt - Hectic, fast-paced but very challenging platformer done relatively well. The controls took a bit to get used to (a bit floaty). You have a lot of movement options like wall running vertically and horizontally, a jetpack that allows speed boosts or multiple jumps, and a generous automatic ledge grab at your disposal. On top of all of that, you have a gun used deal with some obstacles that will get in your way, sometimes even while you're moving. Lots of trial and error happening but the game has near instant respawns and nice checkpointing (it even has mobile checkpoints that you can deploy at your leisure). Great soundtrack too.
Fly'N - A visually delightful 2D platformer with many puzzle elements. You will meet 4 characters that each have their own unique abilities that must be used to progress through each level. What caught me offguard was how demanding the timing of some of the puzzles would be. The two characters that dragged it down for me was the physics-based bouncy creature that seemed a bit unreliable and the dashing fish one that moved in the direction of your cursor (often had trouble seeing where it was) which becomes an issue during faster segments. I played with keyboard+mouse, no idea if a controller would have been better.
Sugar Cube: Bittersweet Factory - Very simple platformer with not much interesting going on. Your character has a constant effect of swapping the state of a couple of blocks near it which may be helpful or harmful. It's a bit annoying to direct it to which blocks you want changed since it's effectively just an aura. You can hold a button to stop the effect. Meh.
Electronic Super Joy - Seemed really basic in terms of what your character is capable of doing but there's a lot happening in the environment, especially things trying to kill you. I was probably wearing thin on platformers at this point but I didn't really like it the first time I tried it either.
Fortix 2 - I'm not sure how I would describe this game, the self-proclaimed reverse tower defense title didn't seemed correct. Your character starts out on the outer edge of each map on a square, safe from any enemy attacks. You can claim space by creating a shape by starting from one point on this square and ending at a different point. The goal is to capture enemy towers and significant items. To do so, you must enclose that object inside the shape your character draws (I saw Qix referenced a lot in comments but I never played that). Fun for the few hours needed to clear all the maps which seems about the right length. Includes maps from the first game if you want to play more.
