Awesome game, love the style and gameplay. I think the jump strength needs to be toned down a lot and the jump off rope strength needs to be increase a bit. I could jump nearly an entire screen up but barely jump upwards off the rope. I think adding the Arrow keys for movement would help a lot or adding another key along with E for Interact would go a long way. Moving with WASD and having to hit E is a bit cramped and can be difficult and can force the player to stop movement to interact. Having the Guard chase you was great. Though, I found that when the timer ran out or I picked the treasure up, I could wait in that room until I was ready because the Guard wouldn't spawn until the next room. So I could pick up the treasure, look at the map and plot my path and then go. I think adding a hidden timer after you pick up the treasure that if you don't move to the next room quick enough, Guards spawn from all the exits to force the player to have to continue moving and not allow them to sit around and plot.
