Loosely based on the classic Nintendo arcade "Mario Bros"(aka that battle minigame from Mario 3). This is a free flash Touhou Project fangame with 1-4 player coop(or single player).
Some new/changed abilities. Various shop changes. 1 new event. Performance tweaks. Multiplayer tweaks. Other changes. 2.0.5b is a hotfix, that addresses a multiplayer bug when running the game from a browser.
I like the game a lot, for every update I like more
