Here,the coin list: coin 1: touched the last block (with skull head) it will turn green eye then the coin went up coin 2 ( on swing mode):there some red laser so go in there then coin spawn. Last coin:when almost ship part then you press or click on screen for 6 times then coin spawn. This is all i know. Have fun :)
I tried out these mods and i must admit, Minos Prime seems faster and harder to beat on Violent difficulty than in original game and Sisyphus feels slower and easier
my only problem with this is that the ultrakill enemies are not balanced with eachother, a single mindflayer can melt sisyphus in mere frames with a laser
