Wow, this game looks awesome, can't wait to play it after work today. =) Btw, I vaguely remember playing a very similar looking game something like 20-25 years ago on a home computer at a friends house. Do you remember the inspirations for Sure Instinct, because I have been searching for that old game for ages (but can't remember the name)
That might be Rock'n'Roll by Rainbow Arts (e. g. on Amiga). I liked it a lot back then, and it had to be played with the mouse, which was a bit of a particular feature. The in-game music was great, too.
