So here is a pitched puzzle-platformer idea:
Basically, the object of the game is to get the character to the end of the level. No problem? Wrong. There are dozens of obstacles and enemies to get around. But you do not control the character whatsoever. The game is paused at the beginning of the level. You have an array of objects at your disposal at the right side of the screen. You place these objects in certain places so the character can maneuver around the obstacles. Be warned, you have a set number of these objects and a time limit to place them. Place them correctly and watch your character move on his own and reach the end!
How is it?
Kimi wa ne tashika ni ano toki watashi no soba ni ita
Itsudatte itsudatte itsudatte
Sugu yoko de waratteita
Nakushitemo torimodosu kimi wo
I will never leave you
