Actually submitted something!
I really didn’t expect to have anything presentable after wasting about a quarter of the 48 hours trying to decide what to do (and more than another quarter on sleep), but after bailing out of the IRC channel to keep from getting discouraged by all the successful people there I plugged away on the game mechanic I had in mind, and when it turned out to be kind of fun I knew I had to submit something, even something horribly, obviously incomplete.
And part of that incompleteness was not being prepared with someplace to host a compiled version, so anyone not adventurous enough to build a libgdx project can safely skip over the eye-gougingly marvelous abomination that is: Splashy Bird! Yes I did feel like the world needed another riff on Flappy Bird! This one’s different! You play a white spherical “bird” diving Beneath the Surface of the water to catch blue spherical “fish”. Use your imagination!
