Lava Pit

Two Vadraks, the albino (white) and the pigmented (gold), fly over a pit of lava. The button flaps the wings, once per press, and the stick steers: holding a direction keeps adding to the speed, and the speed stays. Gravity pulls all the time, and touching a ledge bounces a bird up. When the two birds touch, the lower one loses a point, and a bird that falls into the lava loses a point too; the loser starts again from the top. Each point moves a marker along the bottom row, and the albino wins at the left end, the pigmented at the right. The game gets faster as one bird leads.

The rules follow the original's machine code, checked against the running original with bots. New in the ColecoVision version: a one-player mode against the ColecoVision, a LEAD option of 5, 10 or 20 points (the original's 20-point lead takes a long time between equal players, so 10 is the default), redrawn pictures, smooth movement, a title menu with how-to-play and credits pages, and an original title tune (Magma Joust). Three original bugs are fixed: the albino always lost a point before anyone moved, a bird flapping just after its restart wrapped to the bottom of the screen and lost another point, and the pigmented bird could vanish when the button was held before any steering.

Controls: controller 1 flies the albino and controller 2 the pigmented bird, which the ColecoVision flies in a one-player game. Stick left and right steer; either side button flaps. On the title menu, stick up and down choose, left and right or the button change PLAYERS and LEAD, and the button on START starts.
