In this game you play as Mettaton trying to collect Alphys' to change your EX power. Although going over Chara will take some of your EX away. (I Don't know why I chose this set of characters) You start with 100 EX charge. Getting 300 charge will win the game. Getting 0 EX charge will "Game Over". (Yes, I know Mettaton turns into EX via the switch on his back. I made this up as I went along. Also, this is my first scratch project in at least 2 years.) Use the left and right arrow keys to move mettaton across the bottom of the stage. As I said, collect Alphys' for EX, and avoid Chara. Feel free to remix the game and use the scripts in your own project :) Use the left and right arrow keys to move.
This game was made as part of a school challenge, I am aware it is boring and is in no way cannon to the actual story of Undertale. Undertale sprites and music credit to Toby Fox :)
