This time, Marisa Kirisame goes out alone to investigate (and collect). It is a game in which Marisa is the main character. Collect new cards and repeatedly challenge stages while conquering stages that develop at high speed and at random. Each play is short, and you play repeatedly to solve the anomalies.
lot of freedom and creativity to make the most powerful build you can or building around a theme or challenging yourself - whatever you want.
grinding for money and cards is satisfying like levelling up in an rpg.
the short levels are more my preference over long playthroughs of the mainline touhou games.
