Facts
Single-player - You can play and beat this game in single-player.
Co-op - This game seems primarily designed for online multiplayer (I believe you can play up to 6 players), but it doesn't support local co-op.
Analysis
Single-screen platformer? - I wish this game was in 4K, because playing fully zoomed out is fascinating. Theoretically, this is a single-screen platformer, but it's easier to see what you're doing if the game is zoomed in a bit.
The stage 1 graphics and enemies seems to be straight out of Dawn of Sorrow. I guess it is one of the most well-regarded games in the series.
