I kinda managed to 'complete' it, let me confirm with anyone:
- it is currently only of 4 chapters, with Chapter-4 current unfinished with only 2-stages in it
- there are 8 scenes in 'Gallery', which are partially unlocked after you've blazed through the story
- 2 'defeat scenes' - POOL [lost in 1st-mission] and NIGHT CITY [lost against X1]; OCEAN is the only scene which do not have any 'fun-time'
- in HOME, currently only 3 places available: entrance, bed, and dining room [I personally miss my 'kitchen' scene introduced in 0.5]
