I lost my AI!

Hello, this is my game. I have been in hell for the last 3 days in order to finish this mess

anyways, in this game you help a robot by guiding him using conrol blocks that you place down, and your goal is to collect all the discs in the level

Controls: 

• use mouse to chose a block and place it down (left click)
• escape to pause (usefull to restart the current level)

I realize that this game may seem a bit off topic, but this is for a very good  reason.  Real AI is hard and intricuit. Scince overambition is a garantied  way to run out of time in a game jam, i just went with something simple and on-topic-ish.

on top of all that, this is my first real finished game with Godot, so I had to learn how to use that, as well as the first game jam I took seriusly and finished.
