Okay, you ask for suggestions so ^.^
I had enough fun with this game to go to Day 14 or so, so I'll try to give you what I saw there:
-Super-items (gold,hearts,rainbows, etc) should have a way to tell me if they are or not worthy to get in my actual situation, like marshmallows do constantly with their size.
-You should consider (if that doesn't happen by now) adding more probability or size of marshmallows as you get more to the right or the left from the initial spot, so there is a better reward to have more speed when you buy the Energy Drink, or more time with the Time Extension.
-Also,give the possibility (maybe even make it another upgrade) of controlling the fall and making it faster, as sometimes you just jump too much and have to wait a lot to get to the floor, if there is something you want there.
-Indication of a final objective?? For example, a semi-transparent avatar of the character on a corner of a choosen size, getting colored or filled as I reach the right size?
Style is cool, sound feedback and marshmallow sizes are very appropriate, your dream story is fun to think about, and I dont get the pun as I'm not a native speaker, but if you insist so much in it it must be a good one xD
Hope this helps and keep it gorging!
