Changelog:
- running by default instead of walking (SHIFT/CTRL to walk),
- default zoom is 0.5 instead of 1.0,
- after starting level zooming in has been changed into zooming out,
- minimum zoom is now 0.2 (0.3 before),
- after ending level there is now an information about amount of keys you acquired,
- added help at first two levels (basics about controls and rocket jumping),
- small language changes.
Enjoy!
