NO HIT - Sans and Undyne the Undying (Undertale by Toby Fox)

Undyne the Undying (no hit) Personal Difficulty - 4/10 Enjoyability - 7/10 Hardest parts are the red soul parts, especially with the revolving spears. I found a strategy that makes even those attacks pretty consistent though, so the biggest problem for a longer challenge would be the RNG of the homing spears. Sans (no hit) Personal Difficulty - 6/10 Enjoyability - 7/10 Most of his moves are very doable, with 3 or 4 of them being hard to perfect. I find the first phase to be harder than the second, but the final move's Gaster Blasters are the trickiest part. Might try to do the full Genocide route without getting hit, and I could see Sans being a huge choke point, and the whole second half with Hotland and Core. Undertale by Toby Fox
