Love the atmosphere!
The sound effects and music are great. I enjoyed the idle animations of the rabbit. Having mystery clickable items on the level is a great way to encourage people to explore your game.
Some issues I noticed:
-If you press Left or Right while in midair, it makes the 'Walking through grass' sound.
-If you release all directional keys while crouch-walking under an obstacle, it forces you back out onto the other side....or sometimes, on the same side you started from.
-In one section of the level where you lower a bridge, the hitTest for the bridge is a bit inaccurate, and you float above it.
These things are only code-related; I love the look and feel of your game. I look forward to seeing more from you!
