Hey there, some feedback for you. A bit more critical than how I'd usually approach this but with the intent to help you improve.
Starting your game, user has to wait 15 seconds to observe your static logo which itself is cut off in the frame, making them wonder if its obscuring a load bar they cant see.
The first thing I saw when the menu loaded was an offer to view an ad to get points.
On the menu, the "About" link does nothing interactive, but it does brick the game and forces the user to reload the page (and the 15 second logo again).
The gameplay is pretty standard platformer, with a large and square enough hitbox on the baby to take out some hearts without actually contacting the threat. Checkpoints work fine.
Running just to the end of the first level without bothering to go out of the way to kill things/collect stuff leaves 20 seconds on the clock so I do wonder if you can 100% the points with time left.
There's a lot of effort put into this game and it shows, but for me all the above make the game not really worth the time investment to beat every level and unlock the endless mode.
