Nice game! Incredible you did this game all from scratch in a week good job!
As for feedback, I think each shape should have a reason for it's abilities, like why does triangle break walls or why circle can pass through conveyor belts. If it is based in a lore, they could have a name and a bit of backstory.
I liked the mechanics being added each level but as levels go by I got a bit frustrated by the fact that I had to keep going back and forth to activate all the buttons and doors.
The game is really cool! Keep up the good work!
