Dimensurge: Goner of Oblivion

The rift through dimensions has been overtaken by fearsome forces. Survive 30 seconds to surge onward, but Polygonal bosses can freeze time until defeated. “Nonagon” ever implying every nonexistent goner! Beyond the Nonagon, the surge grows more unstable with new enemies, destructive phenomena, strange abilities and formidable entities from eerier dimensions. Build 2.1 features Part 1 + Part 2 fully playable in one continuous surge. How far can you go before becoming a goner forever?
