Can grease pencil be used in game engine?

I am looking to create a game that is essentially a series of animations made with grease pencil, controlled by the player. You could think of it as a choose your own adventure type of game. The choices trigger different animations. Is this possible to do with UPBGE?

I know of ways to do this in other engines by exporting image sequences, but I’m looking for a possible all in one solution. It would be really handy to be able to draw, control the camera, add effects, create game logic and export a game all in one package.

upbge 0.3.0 supports it. No clue if it can be used by the player ingame, but it works for you as developer and use it ingame.

UPBGE 0.3 supports grease-pencil.
