It's a game by the guy who created Super Hexagon. It's a platformer and to get around the levels you have to flip gravity.
And Super Gravitron is available for free if you are feeling masochistic.
If any else is disappointed in the watered-down mechanics of this, although different, you should check out the game vvvvvv. It's a great precision platformer that will probably make you rage quit https://play.google.com/store/apps/details?id=air.com.distractionware.vvvvvvmobile
I've got similar thing, caused by software - but I've discovered that one game (VVVVVV, https://play.google.com/store/apps/details?id=air.com.distractionware.vvvvvvmobile) running in background is causing it. Opening recent apps screen and getting rid of it solves the issue - so it's very likely that some piece of software is also guilty in your case.
vvvvv
It's got fun gravity mechanics.
Not a collectathon but a fun platformer nonetheless: vvvvvv
There is a little game called VVVVVV (also on Android for much less; I haven't tested touch screen controls however). It's a Metroidvania without any items that allows you to go anywhere right from the start, at least in theory. It's also a game without a jump button: Instead, you can change the direction of gravity. Cute minimalist retro graphics hide extremely challenging gameplay and level design with seemingly unfair obstacles that have to be overcome - and in the beginning, it's simply impossible to tackle the harder ones. Instead of gathering new items and abilities like in other Metroidvanias, the idea is that you, the player, level up in a way and become better at the game, thus being able to overcome obstacles that just seemed impossible at the start. It's a brilliant subversion of the genre.
That's at least how it's intended. You can just grind your teeth against an obstacle you weren't meant to tackle until later on in the game right from the start. Nothing will stop you from doing it and the game's inherent nonlinear nature is built with player choice in mind.
VVVVVV is, at least in my eyes, as close to perfection as any game can hope to be. It's challenging, but it's the right kind of challenging, never unfair. You will never blame the game, only yourself, and the frequent checkpoints and instant resets effectively prevent frustration. Controls are perfect, level design is astonishing, the marvelous soundtrack will stay in your head forever and it's just one of those games that sets out to do one very specific thing and then succeeds at it without even a single flaw or issue. I think it's worth to overcome your distaste for 8bit graphics with this title.
Somehow I have missed your post...
The game is called VVVVVV. It is indeed a port from PC.
