Such a disgustingly terribly game.
The scoring system is bad. You don't know what you're being scored on until you finish each run. On some runs you need to conserve fluid, on others you need to be as fast as possible. Unfortunately, there is literally no way of telling which level is which type until you've reached the end.
Further, the game is heavily trial and error. There are many curves and jumps that you need to be going a certain speed over to clear them successfully, but you have had to set that speed up two or three jumps previous, and often a few screen lengths away. Also, you can't scroll the screen, so you can't look ahead.
Further still, the game is physics based, so your run is a little bit random each time as any slight variation (including random chance) modifies the position of your fluid, making some levels impossible on some runs.
To cap this trifecta of fail off, the whole time the game is making fun of you for your forced failure, calling you a 'whiner' for skipping levels that you get overly frustrated in because of aforementioned trial and error gameplay, laughing at your poor times and mocking your difficulty choice.
What would have been a neat physics game was outright ruined by terrible design practices. 90% of the game's issues could be fixed if the score system was published before a run, and if there was a map or scrolling overview of each run shown before you began.
Do not buy this game. Do not let your friends buy this game. Do not support this company.
