I fed that comment from Steam into Google Translate and this came out:
Variable gravity runner. One mistake and start over. My record is 460 meters.
+1 perfect game.

Man in Gravity

In Brief

An endless runner game made with the Unity engine.

The Game

Man in Gravity is a endless side scrolling runner game with procedurally generated retro graphics, where you can control gravity by making the runner move to the ceiling of the corridor they are running down. Graphics are what I'd call bare bones, with only three colours used i.e. red and white for the blocks that make up the runners corridor and the runner who is yellow.

If like me you have slow reaction times, this may be a difficult game to play. I spent about twenty minutes playing and could get no further than just under 100. The distance traveled is indicated at the top left hand corner of the game screen. There are no instructions given and no main menu, you are taken directly into the game after the Unity engine splash scree ends. The only key binding you need to know is the space bar (to move from the floor to the ceiling and vice-versa) and the left mouse button. Touch anything red and you die, crash into white blocks and you die.

On the top right are three buttons for toggling off the music, restarting the game and exiting the game. The music is a techno/electronique beat that becomes a little repetitive after a few minutes of game play

You can see a couple of videos of game play HERE and HERE.

Conclusion

The game was released on Steam last month (11th August 2020) for £0.79/$0.99 and has so far garnered one community review that is mainly in Russian and who gave the game a thumbs up. HERE

This is one of those games that has limited replayability once you've spent several minutes playing it. This in my opinion makes it an ideal coffee break game. For those who like to beat their own scores, you could continue to play this just to see if you can keep beating your best distance.

The latest Epic game freebies are Watch Dogs 2 (usual cost £49.99/$49.99/€59.99), Football Manager 2020 (usual cost £39.99/$49.99/€54.99) and Stick it to the Man (usual price £7.99); I highly recommend Watchdogs 2, though it contains mature content so isn't suitable for the kids). At 4pm (UK time) the above gaames will no longer be availaable for free but will be replaced with Roller Coaster Tycoon 3: The Complete Edition (this was an Epic Exclusive since September 2019, but today it goes on general release on other game platforms; basically Epic are givingt the game away just a sit goes on general release.

There's a couple of new additions to the Indie Gala freebies called Desert Law and The Tomorrow War (a 3D space shooter with ground strafing on planets. The game reminds me of a souped-up version of the first space shooter I ever bough back in the early 90's called Epic, but with far superior graphics.

Please stay safe everyone.
