What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Players praise this as an excellent 2D stealth platformer with clever non-linear level design and engaging ninja-based gameplay, with some calling it their favorite stealth game. The main complaints center on frustrating checkpoint placement that can force tedious level replays and excessive trial-and-error design in certain sections that tests patience rather than skill.
one of my favourite 2d platform stealth puzzlers cant remember the negatives if there were any because i played it over a decade ago
Very good, too bad it's unlisted.
great game
Yes it is fun to find your stealthy ninja way, which is not always linear. But sometimes you have to be pretty patient when your last checkpoint literally is in hell und you have to do a really annoying level again. And there is to much trial and error in some levels.
Probably my favorite stealth game ever
Great 2D stealth game
