Super fun arcade game! :D
Very addicting, although the best I could do was 1503, couldn't reach the covetted 2000 haha.
My feedback was GOING to be to weight the points differently for the harder objects, but then I realised you actually were doing that, it's just hard to tell in the heat of the moment. :) A good way to make it clearer to the play might be to have the "point value" of the item appear under the picture at the top, OR to do like a POINTxCOMBO type popup everytime something is eaten.
So for a pen with a 7 combo a little 15*7 would appear (or just the actual value, so 105 in this case).
Well done though, very fun arcade game (I could actually see something like this in an ACTUAL arcade haha). :D
