The game didn't feel responsive to me. I felt like I was robbed of a lot of points to furiously clicking to try and eat the people and cars. And the lack of a chomp sound made me sad

Is the itch.io page supposed to work? It just shows up blank with the "click to eat" text at top and some buttons about itch.io on bottom.

if there is a timer on action, it should be somehow noticable if the period is too long.. like here..

This game didn't really work very well and I think the first person shooter graphic as the thumbnail was a very cheap way of trying to get people to click on your game.

Not bad. You should integrate some explanation so as to understand how increase score. There is a timer? How click quickly? I like it. Thank you ++

Just... why?... The visual style could have had something going for it, if it would have been created with a bit more... well, planning. Same opinion on the screenshot as Mark Smith.
The gameplay mechanics (while not original), should still be able to create a fun game, but being stationary really is crippling. The timelag between the bites is a good idea in theory, but without visual feedback like chewing it seems annoying.
It is a nice try for a first game, but I would suggest implementing a few more gameplay options next time (movement, maybe jumping for crushing things, breathing fire anything you like)
