Nice little game!
This is a nice break from how many of the other games decided to take on the theme of scaling (including my own) and for that, it is pretty creative! I think this is one of the harder jams to think of something unique and won't be done by a lot of other people, but you guys found a way and put a whole story to go along with it.
The story of this game is great, just having some form of goal or drive I think can help the player a lot in being motivated to complete a game, and feel more connected with it by the end. I do wish the game didn't loop on itself after you beat it though, since I can make it feel a little strange going right back into the start.
The gameplay definitely was unique, although not super challenging, which is a fine thing, since simple games can be a good relax from the harder ones in the jam, and a relaxing theme really fits the cutesy story of the game too. But, I did find myself basically just placing down anything I could, and then just filling in 1 spot gaps whenever a 2 sized log came in. I even beat the last level when I had accidentally gnawed twice. (Somehow G and R were too complicated for me to remember??)
It does make me think how would this game play differently if there was a bit more challenge to it, maybe having a given set a logs that the player must choose from, so they need to plan out their chews more carefully. But, overall the game was still very enjoyable. You definitely don't want something too hard.
There is an amazing amount of art for this, and it all looks spectacular, your artist really did some great work :) Lots of polish on all the pieces and getting the little things to go along with it, like the logs rotating down the stream and all the little particle effects, great polish!
Great job!
