If the game goes off‑screen or the sides extend past your monitor, you can fix it by changing the fullscreen mode in the registry.

Go to:  Computer\HKEY_CURRENT_USER\Software\StepFurtherStudio\PTG

Find the value: Screenmanager Fullscreen mode_h3630240806

this number h3630240806 might look different on your system

Change it from 1 to 0.

- 0 = Exclusive Fullscreen (proper resolution change, fixes scaling)

- 1 = Borderless Fullscreen (stretches to desktop resolution, does NOT rescale the game)

- 2 = Windowed

Hello! Help me please. I can't start 2nd level when i completing 1st level. (Free version on Windows)

The other “levels” are basically paid versions of the same game. I don’t think there’s an actual Level 2 — it seems more like a different  version of Level 1.  There is a Level 3, but as I said, it’s paid. But for 2 euros, it’s hard to complain.
