Dreamarbleng (ドリーマーブリング which could also be romanized as "Dreamer Bring") is a game based upon Irotsuki's dreams. As opposed to most fangames, instead of refusing to leaver her room, the protagonist refuses to leave her house instead. The game has little story which is all explained in a letter you find in Irotsuki's room. This letter speaks of a certain Mr.Dreamer asking Irotsuki to paint the ladnscapes of her dreams, but to be careful to never paint any of the living beings she may find. However, that letter has been removed as of version 0.005bitIII.
The nexus consists of a room similar to Irotsuki's which has a big canvas and a little one. Once you interact with the little one, you're taken to the first world where you're supposed to find the "Brush and palette" item. As you find items, you can unlock more empty canvases which need to be painted in order to explore more worlds.
This game has 7 effects and 15 items to find. There's also a single ending after you unlock all the worlds. The latest version is 0.005bit V
