Fantastic game, stranger ne_mene. The player feels a good sense of progression when beating waves, although not all is clear. Frequently I find myself trapped on a sinking island, and I simply don't see where the other one is, so I simply perish. Another thing, the ball's timing before returning is not clear to the player, nor is it's pickup radius. The way the ball is thrown feels similar to a boomerang, which makes it's oddly slow return feel off and unnatural. The ball itself when returned is held at such a distance from the player, it feels weird to have it so far in front when the player is locked to such a small island. The upgrades are static sprites so they don't feel too special other than a simple color contrast from the island and enemies. The items themselves also don't convey their use too well either. When I saw those wings I instantly thought "LETS GO I CAN'T FALL IN THE VOID" and promptly threw myself off the edge and grabbed it, thoroughly disappointed at it's true ability. Even so, the particles and polish are great, and a healthy amount of different sounds is even better. Fantastic submission.
