In RumDreams, you're running a little green glob navigating a gnarly 2D platform world. It's littered with sharp spikes, moving spiky walls, and some whacky floating eyes blasting projectiles your way. Your mission? Snag three glowing energy orbs scattered across each level while keeping your blob alive. It's all about nailing those jumps, timing it right, and pulling off some slick maneuvers to dodge instant death from all these hazards. As you progress, the difficulty cranks up, really putting your reflexes and puzzle-solving skills to the test as you try to help the goo break free from this bizarre and hostile realm.
