After receiving loads of constructive criticism, like this over here:
and other comments saying that the game is too hard. I decided to make first 5 levels easier... But probably game is still way too hardcore! I wonder if anyone passed at least first chapter (except me). But good luck anyway and thanks for all comments (these positive and not)!
Changelog:
- improved first five levels (first chapter), now they are easier (at least they should be ;-)).
Enjoy!
