Thanks for playing! I love the way you dig deep into it. I don't want to dispel and dissappoint but I got to clear the air a bit. Game uses default unity physics and there are no changes in physics as you progress, only thing that does is the time limit. The thing affecting the physics is player frustration which is created by the time limit. The harder you push, you get more resistance from other physics colliders around you. So I was going for a placebo feeling of progression in terms of physics, was not sure if it would work, greatful to know for some it did! It was also the only managable solution considering the short development time. I think many things in games development could be solved by faking it, becomes more impactful than complex systems. I'm glad you've enjoyed it and thanks again!
