No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $1.5M — a different platform, not this one.

20XX

20XX is a roguelike action platformer that you can play with a friend. Jump and shoot your way through ever-changing levels, collect awesome new powers, and battle mighty bosses in the name of saving the human race maybe! 20XX features full co-op. Play with a friend on the couch or over the internet! Features: - Crisp, precise controls - do exactly what you want your character to! - Over 100 mighty powerups to collect! - Tons of different play modes and optional difficulty modifiers! - Seeded Daily and Weekly Challenges! - All gameplay features available in both single player and co-op! (online or local) - Random levels: each time you play 20XX, the stages you play through will be brand new! - Permanent death: each 20XX playthrough is a self-contained life! Death sends you back to HQ, where you can buy powerful upgrades for future runs. (There's also a Reverent Mode where you get three lives to make it through the game instead of one.)
