Edit: My 2nd time playing, the cryptic symbols test is possible to clear. Mash space through it the symbols, and you'll get a net increase in points if you do the words well.
I never thought Undertale would cross with typing... It's a pretty fun game. Defied the teacher at almost every turn, put my cheesy fingers all over the principle's things (which no one seemed to care about), and Doggo needs to learn about the Echo Plant. The bit with the cryptic symbols are probably supposed to be impossible, though. Now to see the other bits in this timeline!
21 hours is my score. You can press W and Sleep to get stuck in the air, and pressing them at basically the same time can give you the perfect height so that the smallest enemies don't harm you, and you can still work on the balloon. Another exploit to use is mashing left click and R to reload your gun every bullet fired (which wipes enemies out faster than doing it normally).
