This is some advertising for a game I made: Running Simulator!
https://void-gamesplay.itch.io/running-simulator (you need to download it on a Windows or OS X [mac] operating system to play it. I will try to get it on Linux soon!)

Running Simulator is a very short and simple game (not worth money unless I made it a decent length) that takes about 5 minutes to complete.

The majority of the game is spend building up speed to pass through barriers, which require a certain amount of speed to pass through. This is done through running, boosting, and bouncing off barriers you are not fast enough to pass through yet.

Hope, if you decide to play it, that you have a good time!
