This game did not aged well, the graphics are outdated, it is not runnable without browsing forums for solutions on nearly any PC and OS. But if you are willing to look over the graphics, willing to look for the solutions to run it on your pc, then you will find a gem. The difficulty is really high, probably the first few playthrough won't give you credit if you are not a hard gamer, but this is where it shines, if you learn from your mistakes, it is really rewarding to beat 'that boss', or 'tough battle', it is a great experience, and the game is no unfairly hard to play, but leaves the learning phase to you. The story is linear, so don't expect months of fun, but the replay factor is absolute existing! I have played it through 3 times at least now, and thinking about a 4th one too, I am 100% behind this game, it deserves this ~6$, worth giving it to a try!
This was literaly the first games bought (in the box with Warcraft 2, Starcraft) by my parents for our first computer, and with my 2 brothers we played these games to rags. Literaly my childhood. At first it was really challenging, but after my gaming experience growth, it became less and less hard, but still even now could put some obsticles in the way of my victory.
