Old Remains
Old Remains Is an Intermediate map by veryfakeguest. It has a total of 6 Buttons, and it's the easiest Intermediate map in Overflow. The jumps are not really that hard, and it does not require speed since the water/acid doesn't rise that quickly. The easiest part of the map is the lava part, as the lava doesn't rise.

Deceitful Peak
Deceitful Peak is an Intermediate map by Kardze. It's currently the 3rd hardest intermediate map along with Vicious Quarry And Facility K.O.D. This map requires speed since the acid rises quick. The hardest part of the map is when the acid turns into lava because it rises very quick until the end. If the player goes slow at that time, The lava will catch up and kill the player instantly.

Vicious Quarry
Vicious Quarry is an intermediate map by veryfakeguest and Kardze. It's the 2nd hardest intermediate map, with Tower K.O.D is in the lead. When the map starts, you have time to get the buttons before the lava quickly rises.

Tower K.O.D
Tower K.O.D is an intermediate map by Kardze. It's the hardest Intermediate map in Overflow, Even if you have time to get to the next room, it is still hard because the acid rises really quickly. Speed is required. There is a swimming part where it has water. When you get to the next room, it has acid, so you must save up air at the swimming part. The hardest part of the map is the final part, even it's just acid, it rises quickly. So be sure to be fast.
