Love the idea! This game is so underrated! Although the core mechanic is excellent, it can be exploited easily:
- Stand in the left middle corner, where it is impossible to be hurt in any level.
- Spawn a helper on each pedestal.
- Now the (oars?) are gone, you can easily spawn a helper on each orb.
- Wait for the rolling lava to go away and teleport to each orb without moving.
- That's the solution to pretty much any level in the game.
- Oh, and you can wall clip easily :-/
Maybe walls could block your projectiles? What about zones where you can't spawn helpers at all? Either way, great idea which needs some developing.
