I played this a while ago and it was good! With the changes that have been made since then, it is shockingly good fun for such a simple premise. Chapeau.
The visual design, music, sfx and gameplay work together very well. The twenty second limitation is complemented very well by the tension that comes from the music and the action of the pouring water.
I especially like that the game cleverly avoids using menus by putting player choices into the game. The game starts by picking up the cup. Hard mode is activated by the choice of cup. Good feedback on player performance is also appreciated.
Bravo.
