(Yet) Another Gravity Game: Player 2 has 5 moves to place the Actors on the playing area (within bounds), every touch on an Actor is a move; then, Player 1 has 3 attempts to hit Player 2.
Actors: Planet (just an obstacle), Star (deviates your projectile with a gravity field), Deflector (deviates your projectile with a “negative” force field), Wormhole (respawns your projectile in a random location).
