when i look up hill climb racing pc, the only result is on bluestacks. is there a better way?

No, I have Hcr2 on BlueStacks and it's work perfectly, i recommend you to use it 😁

for the speedrun.com page for the platforms it says its available on pc

how will i get my saved things back?

The only way to get the game on PC is by using Bluestacks and to get your things back you would need to link your account from your previous device. Bluestacks is completly safe and user friendly.

nox or bluestacks
