Note: Instead of arrows, if you have a mechanical keyboard, you may have to deactivate num lock and then use the 8, 4, 6 and 2 keys! An Undertale Battle Simulator! Player 1 uses the arrows to control their soul to dodge attacks! Player 2 plays as the monster! Use 1-9 to select attacks (though only '1' works for now) and press/hold space to fire! W and S work as modifiers. For attack 1, they switch the pellets between coming from the bottom and coming from the top. In the future, A and D will also be usable as modifiers! These will be used to change the angle of the pellets in attack 1 to the left, to the right, or straight up or down as they are now. Player 1 cannot currently die or attack. The music, damage or attack style cannot be changed. Only one attack exists. The monster sprite cannot be seen or changed. This is basically just a tech demo at this point :P
Undertale Belongs to Toby Fox.
