Even more balancing, PARTICLES!! (and more visual Feedback)

The game is now even more balanced than before - and I removed most of the RNG of the game by spawning the bears consistently now, instead of having them in a spawning-pool. They always clogged up the floors out of nowhere, and I thought to myself "that's not how I want the game to be". So I changed: Every fifth animal is a bear now. That makes game as a whole much more predictable and consistent.

The visual feedback is now better with *PARTICLES* and Freeze-Frames. 

Let me know your new highscore when I'm streaming again tomorrow! (twitch.tv/spookyfistpump)
