No.20670 procyon Tester Oct 27, 2022, 17:44 edited on: Oct 27, 2022, 17:47	Since version 0.249, this is significantly improved. The game is playable. There are only three noticeable bugs: 1) The player's bullet remains floating above the ship. When it is fired, it travels up until it connects with an enemy or reaches the top of the screen, and then resets above the ship. 2) The player's bullet does not always successfully collide with the lowest enemy of a column. 3) There is a rainbow artifact that appears on the left side of the screen when the enemies move to certain positions. It seems to come and go as the enemies march back and forth. I don't know how many of these bugs may be present in the actual Galaxian software, but I don't remember encountering them on real hardware.
