I cant find one of the levels in warp tank

[SteveTheFool]

I have found all the other levels and the coffee for each except one, i have looked every where for hours and checked all crevices for a secret passage.
The only bit i haven't gone down is what looks like a bridge made of coffee bubbles.
any know of a hard to find level on its own?

For the easiest to miss levels:
From the start, go up, past the pink and green tank selectors. Take the top right exit. Go down at the bottom left of the next room. In the floor of this room, right underneath the "09" marker, there's a marked segment in the floor that leads to a level.

From the previously mentioned marked segment in the floor, go right to the end of the long room.

From the previously described room, take the bottom central exit for one level (above a crane NPC), and the bottom left exit for another.

The other hidden levels are largely in pairs, but there is one level by itself at the bottom left of the infested area left of the start that you could have missed. It's immediately next to the red tank selector.

Personally, I had missed the bottom rightmost level on the map, near the crane NPC, since it's so far from the start (requires you to do the whole up-right-down-right-down path described above). There is a full map at the end of the warp tank Steam guide.

The coffee bubble bridge leads to the final level, which is only accessible if you've gotten every coffee.
