Just pops up "Lost WebGL context" on Chrome macOS.

The idea is nice . Power-ups hide the tracks beneath them maybe the power-ups could become transparent once tracks are placed. The game is complex and appreciate your efforts.

I like the idea, but like someone else has said, I think it is too hard to get anywhere, I did notice you tried to make it more clear what kind of parts you were working with because of the red lines and corner stones you added to the double corner tiles, but I dont think it was enough. I think the game could have benefited from some removing the time limit or having you control the train and dont let you override the pieces. 

What I ended up doing was just replacing each piece until i got something useful, which is probably not intended. Maybe this could also have been solved by being able to rotate the pieces

I could not rate your game because it is breaking Firefox everytime I try to load the game. Sure this is a problem with Godot + MacOS + Firefox.

Cool idea, but too complicated and too difficult.

My train only made it through 4 tiles before crashing ... :-(

Also, the icons on the field make the tracks difficult to see.

I think it could be great if you make simpler levels :-)
