Update v0.2.1

I added 5 new levels for 2nd chapter, and some very, very sneaky riddles...

Only 7 levels are remaining...

Also, as there is quite a lot "type smth on keyboard to solve riddle" stuff, i added flute - press space to grab it, press letters to play. Consistency

Quality of life changes:

• Now, if you complete all levels in a chapter, there will be flag on this chapter on global map (i dunno if it was already).
• If you collect all berries in a chapter, there will be 1 collected berry on this chapter on global map.
• Now, chapters as well have their own berry (as second berry). Only chapter 1 has additional berry .
• As there is "typing smth on keyboard to solve riddle" stuff, i added flute - press space to grab it, press letters to play.
• Now every riddle that needs some "typing" uses flute as typing tool.
• Now window in browser version is not demonic being.
• Now it has fullscreen button.
