Is the toxic sewer lane worth it?

It pays double gems, and a sludge crawler comes down the lane for whoever takes them; it melts half your stack. Take the gems and get out and it is worth it; staying in the lane is not.

What happens if I run out of blobs in the vat?

The level still finishes. The vat is only part full, the win screen says how full, and the reward is smaller than for a full vat.

How do I make the stack bigger?

Go through the green blob machines, which double it, and avoid acid pits and low tunnels, which shrink it. The machines come in pairs with a bad one beside the good one, so it is always a choice.

Does it run on a phone?

Yes. Drag to steer; the arrow keys work on a keyboard.

How to play Ooze Overload

You bounce a stack of glowing ooze blobs through a mushroom swamp, steering by drag or with the arrow keys. Blob machines double the stack, acid pits and low tunnels shrink it, and at the end every blob fills one row of the vat. Fill it all for the full reward; run out part-way and the level still finishes, with the vat only part full. Running alongside the main route is a toxic sewer lane that pays double gems, which is the decision the game keeps asking you to make: the gems are genuinely worth twice as much, and a sludge crawler comes down that lane for whoever takes them, melting half the stack. Everything is lit in neon against a dark swamp, so the hazards and the gates are readable at speed even when the stack is large.

Tips

Dip into the sewer lane, do not live in it. Take the double gems and steer out straight after, before the crawler gets there.
Blob gates come in pairs and the bad one is often the closer one. Look before you drift.
A crawler melts half the stack; an acid pit only nibbles at it. When you have to clip one, clip the pit.
A low tunnel cuts the stack down to the height of its opening. Steer round the end of it if the stack is tall.

About Ooze Overload

Ooze Overload is a growth runner with a risk lane, and the reason it works is legibility. Neon-on-dark is not just a look - it means the blob gates, the acid and the crawlers each have a distinct colour signature you can parse at speed, which is what allows the game to run as fast as it does without becoming unfair. The stack is the other choice worth noticing: it leans a little as you steer but follows your finger closely, so a lane change is a decision you make rather than a fight with the controls.
