Kai
Heal him to full, fill his Burst, give or take Burst charges, or kill him (he respawns like any other death).
Your chat drops enemies and turrets on Kai mid-screen, fills or drains his Burst and, if they feel cruel, wipes him out.
Four stops, in under a second.
From TikTok, Twitch, Kick, YouTube or Starvios: a gift, a follow, likes or a chat command.
Receives the event, checks your active profile for the matching effect and sends it.
A copy of the game's code with the OverInteractive connector, which the app opens separately without touching your original game.

The enemy or turret shows up next to Kai instantly.
Everything happens from the game's status bar, at the bottom of the app.
It detects Gravity Circuit in your Steam library. If it lives somewhere else, press «Set path» in the bar below and pick it.
Press «Install mod». The app sets up a launcher and a copy of the game's code with the connector inside. The original executable is not touched.
It's the only way to open the modded version. If you open it from Steam, the normal game starts and gifts don't arrive.
The bar below switches to «Connected» once the game starts. Effects apply as soon as you're inside a level.
In «Profiles» create an example one in a click or build your own: each gift, follow or chat command fires the effect you pick.
Each effect is assigned to a gift, a follow, likes or a chat command.
Heal him to full, fill his Burst, give or take Burst charges, or kill him (he respawns like any other death).
Spikey, Lava Crawler, Quake Hammer, Ice Chucker, Virus Battie and the rest of the bestiary spawn next to Kai; or they all get destroyed at once.
Boom Turret, Freeze Turret, Omnishot Turret, Bug Dispenser or Missile Platform: they mount on the nearest ceiling or floor and shoot at Kai.
From Steam the regular Gravity Circuit starts, without the mod, and the bar stays at «Stopped». Use «Launch game».
Even when you open it from the app, the game needs Steam open to start.
Effects don't apply in the menu: you need to be playing a level.
The modded copy keeps the old code. Use «Reinstall mod», in the ⋯ menu of the bar below, to rebuild it with the new version.
Download OverInteractive for free: this same guide is waiting inside the app, in the game's «Start» tab.
