Great game, but a few suggestions:
Use "Shapes" For most art instead of "Paint" This will get alot of fixing up.
Add a title and lots of tags. This will increase popularity.
Last but not least, make the deck private, add 7 cubes in total before releasing.
Also btw just get rid of the 100 reacts for shop thing. Its gonna give you NO reacts if you do that.
:D Happy Devoloping!!
