Playing in windows, but my graphic card could definitely be the problem, it is fairly old. If it helps, I could try and create a video and send it to you.
My screen is 3840x1600. Black bars could help. I can totally see how otherwise for your type of game the infinite scroll starts to flicker on such screens.
PC. Is there a way I can see the framerate? It could easily be below 60, I have a large screen, but an old graphic card, that sometimes has problems handling it outside of productivity applications.
The game is ok, but what really sucks the joy out of it for me is that the collision detection when jumping on red enemies is really whacky. Every second time I am really certain that I jumped on top, but still get killed. This feels very frustrating.
Other than that the levels feel varied and playing always only one screen is interesting, because you can always see everything and plan accordingly.
