Gullo

Spikes, pits, and disappearing platforms are your only welcome in Gullo, a platformer where the double jump is both your best friend and your worst enemy.

Gullo drops you into a world where every screen is a puzzle of timing and reflexes. Your moveset is simple: run left/right, jump, and jump again in mid-air. That double jump is the whole game — it lets you correct mistakes, reach higher platforms, and sometimes accidentally launch yourself into a spike pit because you hit it one frame too late. I learned that the hard way on level three, where a rotating saw blade sits right where your second jump arc peaks. You'll die. A lot. But the respawn is instant, so you're never pulled out of the flow. The level layouts feel handcrafted, not generated. Gates lock behind you, keys hide in awkward corners, and some platforms shift when you land. What surprised me was how the game teaches you its physics without a single pop-up. The first few jumps are safe, then the floor drops away into a spike corridor, and suddenly you're double-jumping over three gaps in a row like it's second nature. The challenge ramps steadily, never unfair but always demanding. If you've played games like VVVVVV or Super Meat Boy, you'll feel at home — though Gullo is simpler, with a clean pixel look and a bouncy little protagonist who seems almost apologetic every time he respawns.

Use "WASD" or "Arrow" keys for the player's movement. Use "W" or "Up" arrow key twice for double jump.

Master the double jump: hit jump again at the top of your first arc for the most height. Don't rush moving platforms — match their rhythm before committing. Spikes kill on contact; never hold forward when landing unless you can see the floor. Look for hidden or invisible platforms — Gullo loves hiding secrets just off-screen. If you die, count the obstacle's pattern before retrying; it never changes. Use short hops (tap jump quickly) for low ceilings to avoid bonking your head.
