Unoriginal colour/shape-matching puzzle - feels like a weak compsci major’s first semester project. Really not worth the time.Polygoneer is little more than a glorified lower-tier flashgame. The player controls a central turrets which revolves to shoot coloured bullets at incoming corresponding-coloured shapes lest they reach the centre. 

There’s a set of Steam Achievements for clearing each of the handful of stages, and for doing so while making minimal errors. Neither the gameplay, art direction, and music are all nothing to write home about. 

Not worth the spare change the dev is asking for.
