> hotkey for making window go on top was switched to ctrl+w instead of space

> new music box unwinding speed formula that makes lower difficulties take significantly longer (it's more of an exponential curve now)

> fixed a hitbox bug with the difficulty changer buttons

> added new hotkeys for doing cool stuff, which are detailed in "tips_and_tricks.txt", but i'll list them here too:

- ctrl+w: keep the Window on top (toggle)
- ctrl+t: show the Time remaining until the box runs out (toggle)

- ctrl+u: Unlock the difficulty changer so its max difficulty is increased to 100 instead of the usual 20 (toggle)

- ctrl+a: Autowind; winds the box for you (what a cheater!) (toggle)

enjoy friends!!!
