Nice concept! Looks like a lot of people has tried to make their own portal with a scaling gun instead, but your project manages to have its own identity as it's a 2D game instead! 😄
It's like I said to another project, we share some core mechanics, so it feels like our teams started together but then split into different project with different ideas hahaha! 😛
The game's solid and the mechanics are well done. The only thing that I would change is making the moving platforms bigger, I can't count how many times I had to restart just because a box slipped out of them!
Pretty good job! 😁
