I just got the first feedback about the game and found the following:
- That riddle on Level 1 is mind-blowing! Why the numbers are arranged in a reverse order?
- Hey you really don't need to unlock the exit door to finish the level!
- No FPS limiter? I want my money back!
So you can read the first riddle straight now, since it's the first level and it should stay simple, the exit door bug is gone and it works properly now and finally, there's an 60FPS limitation and the game will run smooth.
Thanks everyone for supporting the game!
