Pretty cool game! The concept fits really well with the theme.
The controls were a bit difficult to get used to but actually not a bad concept I tihnk. For me the main problem was the toilet roll slightly 'drifting' - sometimes I let go of the key when I expect the roll to turn, but then he drifts into the block infront and that was a bit frustrating. So maybe more of a 'snappy' control with the same mechanic.
I also was a bit confused by the achievements screen. And also I think some kind of goal with elvel design would be cool :)
Anyway, great job!
