I don't think cops should help robbers escape prison... or at least I hope they don't!
Very nice puzzle platformer, it catched my intrest due to similarity with my game as I also have a cop/guard and thief situation, the gameplay delivered. I got a little stuck on the second-to-last level but after restarting I finally beat it. It is impressive that there are a lot of levels and many mechanics introduced through out so the game doesn't feel boring and has a decent runtime for a jam game.
Although I was a little bit sceptic about the introduction of the mouse, I must say it was ok and actually I much prefer aiming with mouse than if I would have to do it with keyboard. The controls are in general very nice and the characters move very smoothly. The introduction of shifting the characters was a great addition.
One thing that could be expanded, to be honest on the last level for a while I thought that the robber will be able to squeeze through a tight hole because he is skinnier than the cop, but I think the hitboxes are actually the same. It would be a great touch and an interesting idea to throw into the mix.
Great work!
