I played this game with good expectations, and I'm actually a bit disappointed. The game is extremely simple, and the "jar" looks like a cube of paper, or something. Without reading the author's comments or getting lucky, the average person playing this game wouldn't know where to put the jar. It's seriously just a white cube, come on.
The controls are pretty shoddy, and you'll likely spend most of your available minute trying to figure out a proper angle for throwing. Another thing, why do I only get a minute? I feel like the game should give a more appropriate time, like 2 minutes 30 seconds, or 3 minutes, at least.
Don't get me wrong, I don't hate this game. I just think that it could be much, much better. It feels hastily made, and if more time was spent on it, it might be more enjoyable.
