Simple, good idea, good assets, good music (probably, but it is annoying for the 15. time, but thats just a skill issue). The animations are especially cute. great job.
Sometimes when i press space at the edge of a platform i dont jump.
If you continue developing this, i would suggest a few changes: when you die, the positions of the drones dont reset (but there is a button to reset all drones), and when you press R with no drones, you start controlling (for 6 seconds) the drone you placed the earliest and so on.
