Press green flag to start. You will have 1 second before the spears start coming in. It mostly functions like the game but it's Undyne's turn forever. (also no invulnerability time) When you die everything will stop and you can look at the timer to see how long you lasted. Press the green flag to play again.
Undertale was made by Toby Fox, music, art and idea credit goes to him. The arrows are generated randomly so sometimes it might be impossible to dodge and sometimes it will be really easy.
