well, a very good start if this is your first game.
things i noticed: the new painting should be on top
and I wish there so more gameplay for this
I recommend you to read more about "Gamification" and hope you a great future
Oh yeah you're right I should've adjust the Layer and make new painting appears on top.
I'll read more about Gamification and also try to add more content for my next Project.
Thank you for the Advice :D
