I AM THE MUSHROOM KING!!!
Even though it was just a small room with two spawn points for the mini mushrooms, I had a really fun time playing around in here seeing how many mushrooms I could get on screen at once.
I would recommend adding collision detection to the summoned mushrooms the same as the player character (that could start to get crazy on the system with too many of them) because if you summoned a few without moving it was almost the same as just calling in one, because they covered each other up. Same thing if you moved all the way right then they would just overlap one another.
It would be awesome to call them and collect them then manipulate the movement to stack enough of them so you could jump off them, or build a bridge with them, or any number of other gameplay options.
Overall, a fun time and solid entry. Great work.
