Post-jam update 0.2

This is the first update after the official GGJ jam weekend schedule. I have added slightly more playable content and now the player shouldn't be able to go off-bounds. Some minor bugs are fixed and menus are updated. Save file should be still compatible with jam build, but be cautious with it. (One might even get stuck in walls.)

I am not sure if there will be any further updates. The basis is quite limited to do variation in actual game content. Nonetheless, this has been very educating and important jam project for me. I am quite happy with the result.
