Thanks!
Now I have finished the game
Final time: 1:57:08
Trials count: 251
Final boss was extremely hard relatively to the first part of the game.
Probably something wrong with life calculations. Player die but the energy exists (line that displays the energy amount), maybe energy drain animation is lagging behind the real energy amount.
And pointer position is not visible. This is very important. I bad understand where exactly the pointer and how much I need to move mouse and in which direction. This lead to incorrect movement, what is very important with such fast game pace.
