first I didn't know for a long time to press space to use that clock, and then I didn't really understand how I should use them. I only found out that I can walk through some most left most right most bottom doors I couldn't with the clock activated but I didn't really understand so kind of too lost.
I loved the music of the menu screen!!!! so cool. maybe built it in in the main game? would have made the game so much cooler in my opinion... (just not to loud in the background)
