Hey, this game gave me World Of Goo vibes, I liked the use of goo, and color picking (like green is acid) , I must say I struggled through the puzzle of the falling green goo, till I understood I gotta stay below and pray to catch it. The one after with the blue goo going up was really hard , there is no restart button so i had to throw black goo on it hoping to get some other blue for me to use and I didnt come to solve it. I would suggest lowering the difficulty a bit or adding more explanation of what to do at start, and a restart button for a level can be nice.
