The game is complete, I just labelled it "alpha" for now to indicate that some minor quirks might exist which might be fixed to reach the status of a complete game. But it may also happen that I determine there is none, and I just remove the "alpha" label later. There isn't much room to add anything anyway, there is only about 300 bytes of ROM space easily accessible as of now, maybe about 300 additional bytes if I started a mad hunt for holes to exploit. The story is complete, just play it to the end!
I did many small tweaks to the mechanics of the game compared to the UCC-2016 demo by my and some friends' game experience, so it should really control better. Once you adapt to it, it shouldn't be difficult to do a run-through (At least for me it goes by routine, there shouldn't be any place forcing you to rely on ridiculous timing to get past. Maximal possible high score peaks somewhere above 20K). There are some quirks I don't exactly like, but those are such hard-limitations which are not possible to get around (the physics engine has some hacks which imposes some limits).
I preserved the UCC-2016 demo: it is accessible as a tag on the GitHub repo, and as of now the wiki entry for the full game also links to web-playable versions of both (on my site, later you may change it to the Uzebox game changer, I put FoaD up actually before Nicksen released the game changer). This may be interesting for other games, too, such as I first didn't understood how Tornado 2000 scored so low on UCC-2014 until I saw what was complete of it then. The FoaD demo wiki entry also still exists, maybe I will just redirect it to the full game's entry (as I added sufficient info there for the demo as well).
No new music, I thought it good enough in the end (although it received some minor tweaks). You will hear something new though if you finish the game.
Did any of you succeed by the way?
