They recently updated Ex-Zodiac and added a new level, some new enemy ships and up’d the difficulty a bit on the earlier levels. The boss battle in the latest one allows you to fight a bull and his bull mech. If the battle doesn’t give your hands carpel tunnel you can at least cause the boss to cramp up if you fire enough ammo at his fists.
I’m thinking of streaming it one of these nights, adding it to the potential list of streamworthy games along with Whisker Squadron Survivor and a few others.
