Fun and satisfying how the chain swings in the air. That mechanic feels pretty solid. I definitely got frozen in my first play through, it's a bit hard to understand that mechanic, perhaps add some icon when section is frozen?
Nice music to bop along to! In the end I basically only used space bar, Q and R with all sections selected. Might be cool if you incentivized partial selection or mixed up the controls every so often or something.
I suppose the splash screen is a bit long. Gameplay might give me carpel tunnel as well but overall great job and good game.
