Wow! This is a very interesting ice slide puzzle variant. So much fun, and it matches the setting so well!
However, there are two disappointments.
One is that, as mentioned in the comments below, this game is quite difficult to understand before you play it first. You should make a simpler tutorial level before the first level.
Another is that the behavior of ants to sugar is puzzling. Often, when the ants enter the range of the sugar, they somehow go straight back instead of turning in the direction of the sugar. In fact, they are less likely to bend toward the sugar.
Also, if I inadvertently place the sugar at the edge of the screen or near the play button, I can't pick it up again. I've gotten stuck twice with this.
I think the basic game idea is very good. Here's hoping the game gets an update!
