I tried this game myself after making one of my own and I wondered if anyone else made a decent 84+CSE Cookie Clicker game. Sure enough, I found this. It seems fairly good.
Gameplay: 8/10
Almost like the original. However, I think that upon exit, instead of storing the game to vars A-Z and insisting nobody run anything before the program starts, you should prompt for the game to be saved to any of the slots. Also, sometimes it didn't appear that only one second passed before the cookies updated (at least 4). I don't know what the problem is there, that should be fixed. And there is no selling buildings. :(
Controls: 6/10
Pretty much what I expected for clicking and quitting, but everything else was new. I used PLUS and MINUS to buy and sell, and LEFT and RIGHT to cycle between buildings. You, on the other hand, used the number pad for buying, and you can't sell. I'm not saying it's bad, but it took a long time for me to memorize.
Savegames: 9/10
The save slots are an excellent feature, but there really should be an autosave like the original, and you could just have 11 values in each save slot list (quantities of each building, and current cookies, as the rest could be calculated in-program).
Originality: 10/10
It's Cookie Clicker on a calculator. The only other one to do that is...well, me.
Overall: 33/40
It's fairly good, although there are some things that need to be improved upon. For example, the author should cut down on variable consumption, as well as follow my other suggestions. Also, it would be nice if the game was just one program, and the save-state lists didn't have to be transferred.
One more thing: set the right graph window at the beginning (my graph window didn't allow it to be seen). Just a friendly tip for future endeavours. ;-D
