Hey great game, I loved the arts and enjoyed the sound effects in the game and the game page :)
I faced the same issue with WebGL, it appears only a black screen, but after waiting a couple of minutes I was able to play it and really enjoy it. I only have feedback about the controls, I wasn't sure how to hide and seek eggs and press all the keys (hopefully was the E key the one), but it would be nice there is more information about the controls and all the player's abilities (also noted you can jump, nice).
