Hi! Thanks for a comment! This gimic with music is pretty simple - I just set the frequency (as i remember) on the number i need when time is below certain value. Mouses are very tricky creatures, they need like 2 hits, but sometimes they moving like sonic and killing them can be a problem . And yeah - that bug with hard-to-pick-up are very tricky too - sometimes this system works, but usually not, so i think i will try to fix it later. Im glad that you had fun playing that game even with this issues!
btw my personal record is 817 points :>
