Hi! The game has 4 Worlds, each world has 2 levels and a boss basically. I'm actually "remaking/reimagining" this game with better controls and camera and stages though. I suggest trying "Cyber Storm Edge Ultimate" demo and compare it with this game's demo to see if you still feel like getting this one or waiting for the other one to be finished.
But yeah, this one is a complete project, if you like this game's demo you'll probably like the full game.
I can't remember the time exactly, but it has around 60 collectables and also speedrun medals to get if you're a completionist.
