Dummy UTMM Codes (October 2024)

Updated October 12, 2024: Added a new code!

Based on the lost (but never forgotten) Undertale Monster Mania, Dummy UTMM gives tons of co-op Arc Dummy-mashing action set in a mysterious underground setting. After defeating a few Arc Dummies, I stumbled into a difficulty spike. Luckily, Dummy UTMM codes gave me the necessary upgrades to continue the climb!
