Click on the soul to increase your DETERMINATION. With DETERMINATION comes UPGRADES that help increase your DETERMINATION. Click on the SHOP button to open the SHOP. In that you will see an UPGRADE button. If you have 1000 or more DETERMINATION you will be able to access it. The UPGRADE gives you 1 DETERMINATION each second (and there will be a stacking effect every 500 DETERMINATION soon).
Thanks to Toby Fox for creating Undertale and Orteil for the idea of a clicker game (e.g. Cookie Clicker https://orteil.dashnet.org/cookieclicker/). ---------------------------------------------------------------------------- The upgrade doesn't work yet so please keep that in mind.
