In Super Cloudbuilt you play the spirit of a girl called Demi, who once beating the opening section of the game you realise you are taking control of after some accident with her being part of the military. You play levels as her spirit (who happens to be wearing an exo-suit), as you use her cool powers to work through levels found in the hospital corridors to uncover the story a little more
Each level also throws a few collectable things to pick up, with the two big ones being item keys and life keys. Finding these will unlock lockers at the end of that level, with each one giving you something to use Finding one of the four lettered key cards will let you open a locker at the end of the level for a random item. Finding the life key will increase your life cap permanently by one. More lockers can also be unlocked by beating certain challenges too, giving each level some replay value if you want to explore it rather than just trying your best to beat it. These challenges show via a shiny blue orb by the door of that level, with things like beating the level as fast as possible, to not firing your weapon being two such challenges you can expect. What these do is make you tackle the level a different way, or it did for me anyway when trying a pacifist run. Not able to use my gun meant I had to go around certain doors and find a different route, to also just avoiding the enemies found on that level trying to kill me.
Overall: Super Cloudbuilt just wasn't for me sadly. My time is a valuable thing to me these days, so swearing at a TV while being stuck on the same level is not something I find enjoyable. Those who like a challenge will get value for money mind you, and I can't really fault the game in terms of looks and things, I just never found it fun to play.
