Thx for the feedback :)
I agree with pretty much everthing ^^
I put in the music in the last second and did not double check if godot imported it as a loop..
The levels need some more iteration and a few more "beginnerfriendly" levels to ease the player into all mechanics.
And of course there are game related limitations i should fix (you cant add new tiles while the game is running, its annoying that you cant just drag nodes out of the execution line, but need to put them where they belong ect.. )
