What is the current wall you've hit? And is it related to collision detection? :D

More seriously, have you tried posting on one of the Godot-related forums/boards listed on https://godotengine.org/community?

Learning new things/engines can definitely be frustrating--so that feeling is completely normal. :)

Alternatively, could you work on a different part of the game and return to the current roadblock later? Maybe focus on something different related to one of the five specific judging criteria to get re-invigorated?

Good luck!
