stc - a relaxing 2D physics puzzle game

In the case of your interest, I just published my first Godot game at itch.io.
I wanted something simple to start with, so 2D physics was a perfect match.
The sources can be found at github.
As a newbie in Godot, I'm curious for your comments on the game, code, whatever. Thanks!

JusTiCe8 thank you for your comments.

Didn't tried it yet but relaxing... maybe not for the eyes although, this flashy color is hurting me just looking at the screenshot.

I just tried to achieve "modern" and shiny look like in Beat Invaders. Simply, I was attracted by glow post-processing achieved by Godot, so I left it in the game.

EDIT: after testing it, the game is a bit too tight regarding shapes positioning IMHO, I'm more frustalaxed

I see. I have a little advice (also mentioned on the game page now) - use fullscreen. And also it is worth mentioning that the physics is more friendly than in reality and each of the first ca. 14 levels can be achieved in seconds. Using of conventional thinking about physics can also lead to the level solution, but is usually too complicated and not necessary. You can, e.g., stack triangles or circles upon each other without problems. Also tolerance in size and position 10% is helpful... I was thinking also about small instructive videos showing how to solve particular situations...(?)

But I realize that this is the view of somebody who designed and accomplished all levels. Therefore, I really appreciate your opinion. Gathering comments, ideas and further requirements can lead to improvements in new game versions. Thanks, again.
