That was indeed a very nice and polished game to play.
Nice build up in level difficulty.
Graphics were cute and simply but still effective and 1 coherent style throughout the game.
Relaxing background audio fits also and some nice jump sfx.
Controls were smooth but still it had sometimes difficulty to jump from the point I wanted with the squish.. But that also added a nice difficulty challenge.
Level selection screen and menu's look nice and polished also and fit into the general visual style.
The theme for this jam would have slightly touched ;)
But overall a very smooth entertaining experience. You can see you put a lot of effort into this game! Nice job!
