Neverout

I tried it both with VR and Desktop mode. In both cases the controls feel weird to use at first, but it is possible to get used to them. It's also good to notice that the VR version has settings to make the game less nauseating, which is great.
It is a very underrated puzzle game, with simple cube chambers where you use changes of gravity to reach the exit. The puzzles aren't very easy, but you will not be stuck in the same room for too long either.
I wish more people who buy this game would play it. Most buyers use coupons and end up never playing Neverout. But this one is worth if you like puzzle games. Only takes about 2 hours to beat,

short game (took me less than 3 hours) but really fun. kinda wish you could walk sideways though, you can only walk forward and rotate. very oldschool controls.
note: I played on PC using a controller.

Here's what you need to know:
Controls are peculiar due to flat or VR option. No WASD, W is forward, S doesn't work, AD rotate you 90º. Since it's a grid based game, the controls are fine and you get the hang of it quickly.
Game is extremely easy. You play around with portals, with magnets, and basic logic. I finished it in one sitting of 1.5 hours.
Aesthetics inspired by the trilogy of Cube, but that's all. The traps are basic, electricity, crushing, spikes. Nothing spectacular happens like seen in the movies.
Basic audio, no soundtrack.
No story. Purely puzzles gameplay.
No options, but not really necessary. Runs just fine.
Bugged the game once, where my character shifted one square to the side. Not game breaking
Played in flat screen mode. I think the above should give you a good overview of what to expect. If you like puzzles in a 3D environment in which you use physics, then I can definitely recommend.

Very nice playable environment, however I find myself a little dizzy after playing 4 hours nonstop.. Eye shake a bit now.. May be a small mouse sensitivity option in setting would have made a perfect fix for it. Generally, very enjoyable and interesting levels.

It's a headache to play, the controls are very arbitrary, you can play with from keyboard or from mouse, or both, the puzzles are nice

Confusing ass game, got it for free and played it 5 mins before it got extremley dificult. 1/10, not for me but some people might like it.

This is a very good game. I finished it in 22 minutes, although undestanding movement and game mechanics takes a while (maybe 5 minutes). Overall this is a worthy game for this price. The graphics are quite amazing, especially the singularity teleporter that looks like a mini black hole with it's gravity lensing. FPS capped at 60.
