Very basic, but a good start. Looks like you have the "stat" and progressive side of things down. Now you need to give people a bit more of a goal to reach. A bunch of achievements for reaching certain goals. Perhaps some upgrades for certain goals. A reason more than just "reach 10,000,000" if you know what I mean :)
It is hard to play this for more than 10 or so minutes otherwise.
I really look forward to what you create in the future!

Brilliant. Another fina piece of art, tearing at the heartstrings, and telling a story piece by piece.

Wonderful work :)
How will you be selling these?

Really like your pixel work!
I wonder if your highlights/shadows would show up more with more contrast? It might give it more depth. I might be wrong, but it is worth a try :)

Fantastic potions at 16x16 pixels! So much detail with so few pixels!
