I got it running and the music is playing. This is as far as I managed to get. No response from keyboard, mouse or joystick but the window functioned without crashing. I hope this helps.

In Labyrinth Stalker, you play as an intrepid adventurer who explores a dungeon filled with dangerous monsters and deadly traps. Each floor has a monster that must be defeated before progressing into the Labyrinth. The action is methodical with a dodge, block (which can become a parry) or attack that takes time to charge up. The monsters are not terribly difficult to defeat but the real challenge of the game comes from devising an escape from the maze. You can only see the layout when you're being attacked by the monster! Once the monster is dead, you'll be left alone to devise your path to the exit.

I've finally decided to take my first game public. It's programmed from scratch in C++ in a single .exe file. I made it in 3 months but it's taken me 3 years to have the courage to send it out to the public. Please tell me if you get a really high score or if you manage to use the key to open the lock.
