When u finish the second tutorial, it shows this error:

___________________________________________
ERROR in
action number 1
of Step Event
for object obj_control:

Error in code at line 6:
if obj_char.lives = 0 then

at position 14: Unknown variable lives

"lives" is a built-in variable, so you can't use it as a local variable.

Free-style adventure, huh ? Well, aside form graphical part, there are still lot of problems:
1) It’s impossible to exit game without saving.
2) Got stuck between vertically moving platform and ceiling. Well, just like it was shown on YoYogames.
3) It should be possible to return in main menu.
4) Still can’t figure how to use ammo. Player should be noted how to crawl before reaching switch in tutorial
5) Got unknown error after second level of tutorial.
6) People should be killed for using that font in games).
