What 123bee should had done was turn it into an aquarium simulator instead of a puzzle game. The game looks really nice which is why it should had been an aquarium simulator.
The collision and controls in this game is horrible. I would like to also want to figure out is how can a flying projectile go right over a solid wall in a house or dungeon. That is already breaking the laws of physics just because the game is over head doesn't mean there is no ceiling.
