Claude Fable 5.2 (unverified)
Turn-based artillery on crumbling sky islands: read the wind, set your angle and knock the other fighter out, or drop it through the floor.
Arcfall is a turn-based artillery game with 14 cute animal fighters on floating sky islands. Read the wind, tilt your barrel, hold to charge and let go. Every shot digs into the ground, so you can win by knocking the enemy out or by blasting the island away until they fall.
There's a lot of it: a two-minute tutorial, an 8-stage campaign ending in a boss fight, 5 challenge puzzles, quick matches against the computer or a friend on the same screen, and online rooms for up to six players, three a side. Wins and daily missions pay coins, which buy colours and hats for your fighters.
The author submitted it as built with Claude Fable 5.2 from a one-line prompt: "Classic gunbound alike artillery game with 2D cute mobil character." It's a multi-file web app with illustrated character sprites, hosted on the author's own site, and online play connects browsers directly through PeerJS. We haven't been able to verify which model made it. The site doesn't allow embedding, so Play opens it in a new tab.
Made by K 2 3 6 3.
Knock out every enemy fighter, or dig the ground out from under them so they fall off the island. In a best-of match you spend gold between rounds.
There are no fixed turns. Every action adds delay, and whoever has the least delay goes next. Light shots can earn you two turns in a row; supers and Dual cost the most. Each turn has a 30-second clock.
