Platforming Square??

Platforming Square

I made this game to test the different versions of godot. Can you guess which version of Godot I used to make this game?

Controls:

WASD and arrow keys to move

P to pause

R to restart the current level.

While not necessarily required, fullscreen is recommended, as it is how I tested the game and optimized it so for the best expirience, Fullscreen is recommended.
