Bob burps bubbles. It solves most problems.
This is Bob. It is not entirely clear what Bob is, but one thing is certain — Bob burps bubbles, and in Bob's world that is a genuinely useful skill. Trap a grump inside one, pop it, and it turns into a snack. Chain your pops for bigger scores, and work your way up a hundred hand-built levels of crumbling ledges, running belts and platforms that tip when you stand on them.
Blow a bubble at a grump and it goes inside. Touch the bubble and it bursts into a snack. Pop again quickly and the points chain — ×2, ×4, ×8.
Not generated — drawn one at a time, in blocks of ten, each block introducing an idea and ending on its hardest board. The difficulty only ever goes up.
Some crumble a second after you stand on them. Some run like belts. And some sit on a pin — they look level until you step on, then they lean and you slide. Where the pin is tells you which way.
Get close and a grump notices you and comes after you. Let a trapped one float free and it comes back angry — faster, and it will follow you off a ledge.
Play with on-screen controls sized to sit under your thumbs, or connect a game controller and it takes over — every direction, every button.
Your best score goes on the board, and the board is in the game — the top nine and your own place, on the same card as everything else.
