Very interesting minimalist clicker game, but combat may frustrate you because it needs ultra reflex to get it after enemy reaches 4 digits. Add keyboard shortcuts for guard DEFINITELY will fix this, or just lock it till numbers reach lv2 or 3 so leveling up feels much more rewarding.

Edit: I just completed the game after ungodly amounts of math quiz just to pull the last number, yes Divide ability unlocks by Lv4 and it's literally OP that makes divide and heal are only buttons you need to push.
