Hypoxia is a marmalde game made by BUas students. You have to run through bots without getting caught. While running you have to connect yourself to other tubes because the hose is not long from the beginning to the end.
My idea was to have a tube and a hose is space where the player has to attach himself to when moving from tube to tube, but I had a bad time implementing the mechanic. It was hard to make a line that acted as a hose. I got some helped from the teachers and other programmers and I learned a lot how to properly implement it.
