Gameplay improvements and bug fixes

Main improvements we've made:
1. Now you can interact with objects using LMD instead of 'F' key
2. Rotation now turn constant 90* instead of smooth turn around character. It works not well enough, so we will work on it late
3. Now you can't run to the shuttle over the walls like Yamakasi

We also fixed few minor bugs you probably didn't know about yet.

Our next plan is to prepare a few more levels with more difficult and chalanging puzzles for an itch.io and steam realease and for GG conference presentation.
