...
usually when looking at
any level which has tight spaces
and hard to see certain spots
felt annoying and giving bad mood.

this one is different,

Spoiler: Comment Contain Sneek Peek

there are 3 balls, the nearest at beginning
is actually the last one to be dropped.
and the main gameplay
is to redirecting P all through tight alleys.
i didnt feel annoyed at all,
curiousity and design prevent
bad mood to appear while playing this.

That hidden draggable was a pain but the rest was very FUN & the design looks great...Thanks for sharing @Lang Tao Jin
