The polish on things like the intro screen and the landing animations are just absolutely *chef's kiss*. Before I had even stepped off the first hill I stopped to start my comment. Aesthetically, you did a fantastic job—the soft colors, the sprites.
That makes it seem like you *didn't* do a fantastic job with the gameplay and that isn't the comparison I meant to set up! I do wish the basic jump were just a *smidge* higher, as traversing the hilly terrain felt a bit more difficult than perhaps intended, but even then I'm not entirely certain because having the struggle maybe makes the upgrades feel even better. However, even with that maybe-complaint I still had a great time—and will be revisiting this one post-jam!
(The terror that peep sound instills in me cannot be described—the number of times I was chased by a bird I could not chance to fight lest I risk losing my backpack full of gems, all the way back to my ship...)
