I just added 3 save slots in v1.0.10.
Your current save data should transfer over, and you'll see % completions for:
- Levels
- Bosses
- Special Zones (SPZ)
Other updates
- Left Trigger for Dash works on both control schemes
- New save slot for Controls settings. You may need to set the non-graphics settings again.
- Planning some QoL changes: toggling autoplay on cutscenes, invert X toggle, & right thumbstick sensitivity slider
Thanks y'all and let me know if you find any issues with things.
