Yea I tried to make each level different, it's a short game only 10 levels. there's different SIDs on level 6-7 but I understand not liking the rest, it is my first attempt at GOATRACKER
No problem. I understand this regarding Goat Tracker. Other newcomers in the C64 game music scene also started that way. I know how hard it would be to make own instruments without full knowledge of the SID :)
