Take on a friend in Undertale Battle Simulator. I didn't use all the features since it's only an alpha version. If the score of the game is higher than 4.0, then I will improve the game. I'm sorry for the bug with sounds at the beginning.

Controls: Use the mouse to create attacks. The left mouse button will create an attack in one direction, and the right one in another. Keyboard buttons 1, 2, 3, 4 are used to change the size.

I was inspired to create this game by the free game Undertale Battle Simulator. I made a remake of this game on Newgrounds.
