In the future, tiny robots do the dirty work. You're one of them — dropped inside a filthy bong to laser the resin, keep the water fresh and clear the downstem, while some stoner keeps ripping it.
Move: drag anywhere on the screen (the bot floats above your finger), or WASD / arrow keys. The bot auto-fires its laser at the nearest grime in range. The beam bounces off glass up to twice, but never passes through it (except the Blucifer Beam).
RESIN — brown gunk on the glass. Laser it. Dark stubborn spots take longer. If resin covers all the glass, mission failed.
BIOFILM — scum growing in the water. Only a water change fixes it: hit PIECE WATER (Space on keyboard). It has a cooldown, so time it.
DEBRIS — charcoal chunks pulled into the downstem. Glass stops the beam, so get under the stem's open end (or under a perc's bottom slits on perc bongs) and fire up into it; inside, the beam bounces its way to the clog.
The stoner shows up every few seconds for a rip: bubbles knock you around and jam your laser, smoke blocks your view, then fresh grime appears. Survive every rip, then clean everything to complete the mission.
710 Pipes delivery — after the stoner's last rip of the round, someone knocks: the door opens and a delivery robot holds out a 710 box. Tap the package (or press F) before the robot gives up. The product lands on the table; tap the bottle (or F) when you want it: Randy's Black Label, Pink Formula or KLEAR Kryptonite gives an instant full clean. One per round.
Blucifer Beam — halfway through each mission, Blucifer's picture on the wall starts flashing red. Tap the picture (or press B) for 5 seconds of a fat red beam that goes straight through glass and burns everything in its path, 3x faster. The stoner's next rip cuts it off, so fire it right after a rip. One per mission.
Build a Bong — design your own from the main menu: pick a shape, drag the handles, add tree arms, showerhead domes, matrix percs and honeycomb discs, set the downstem, the water and the difficulty, then hit Test. Save it to My Bongs or share its code with a friend.
Bot Skins — pick your bot's paint job from the main menu or the pause menu. Cosmetic only.
