Warptank Cherry Clear - Coffee Locations
Locations of each hidden coffee in Warptank, for 100% completion.
Finding Hints Without Help
If you're focused on gameplay, you may have missed a nice little detail amidst stages. One particular element of the background appears exactly once in every stage to signify that there is a secret coffee nearby.
Haven't figured it out yet? It's a flower on each stage! These do not always give you the immediate location of the coffee, but often times they do hint at how you're meant to achieve it. See if you can use this to discover hidden coffee locations first!
Important Note: If you die before reaching the end of a stage with a coffee, it will not count for the stage, even if you got a checkpoint along the way. Once you obtain the coffee, it MUST be deathless for the rest of the sector. Respawns with grabbing the coffee after the respawn still count, though.
