No revenue estimate for EPIC — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $2.5K — a different platform, not this one.

Echo Storm

Echo Storm is a 2D action with roguelite elements. Survive enemies attack as long as possible. Death resets the progress, but the longer you survive, the more abilities your character gets. Onslaught of enemies is growing too, so - find best abilities combination and destroy 'em!
