Simple and effective! However, doesn't it just change the player's appearance to a flag and the flag's appearance to a player...? :p Jokes aside, I really liked that the spikes didn't harm the flag even though they could have killed the player. On the other hand, I find it demanding to have to gather momentum right from the beginning of the game for certain jumps. Maybe that would be more suitable for advanced levels? Either way, it was fun :D . Well done!
