Congrats ska! Yes I'd think you're the first.
I personally gave up after the first column. This type of competition just isn't for me. I don't have enough willpower.
Still haven't even completed v1.4 :P
About the physics engine:
- It's not too different from v1.4, which is good
It's a bit easier to perpendicular jump
You can still survive falls by hitting corners of tiles
Don't need to press directions to jump on one-ways (thanks, ska)
You can still cj
Triples seem to be harder, but that could be the lag
BBs are nice; but not the same
Negatives
- No corner shoves
Lags quite horribly on Windows 7
No "boost" from jumping on thwumps (thanks, ska)
NO USERLEVELS REPLAY BOX!?!?!?
Still no way to get death demos
No way to even watch demos (This would probably be included in the last version; with debug mode)
(Basically, the physics engine was the one from holiday contesque)
Also; ska and I both noticed that there was something different with gausses. I thought they fired more often than from 1.4
Andddd, there is a 2 player mode that you can change to in the "Levels" tab by pressing up. It seems to be limited to multiplayer on the same computer for now.
Looking at the "Levels" tab it looks as if M&R are looking for someway to incorporate userlevels (nmaps) more into the game.
