I personally like how the controls came out! I, however, experienced many bugs of not gripping to the walls in the correct direction and even gripping where there is NOTHING in the last 2 levels. It also didn't quite feel like a retro game. Still, nice effort man!

Agreed, the idea is neat, but the execution is a bit flawed. Maybe if the controls were aligned to the wall you were on? It was particularly confusing when you were upside down,  since right was left and left was right. If they were wall-aligned it might have been more intuitive.
