Very nice! Looks fantastic and a nice little puzzle element. Great artwork, colour and theme. I really like it. There are a couple of issues with the gameplay. First the paint stays on the floor if you restart the level which made me think I didn't need to put it back down, then when I spawned the 'people' they just fell to their death. :( Also It would be good to have a clean up option where if I put down paint by mistake I can remove it, I know you can just put more paint on top of the paint but I found that messy :) Overall a very very solid game! Great job!
PS the voice sounds reminded me of Worms. which was brilliant.
