Congrats on your first game!! Tutorial or not you did a great job. I got started with Godot tutorials too so this game brought back good memories. Here's a little coding challenge for you: try adding slippery movement when you're on the ice blocks

So far out of 20+ games on here, I didn't run into any bugs or weird glitches with the game freezing. From one Godot dev to another, I recommend going into Project Settings changing the rendering environment to black or whatever color you're using for your background.

Overall, well done for your first game

Cool game dude! We've all started with youtube tutorials at some point, so don't worry about that ;)
