An enchantment system has crossed my mind before, but I feel like it would add another layer of complexity to the game that I'm not quite ready to dive into just yet.
That said, *spoiler alert* Relics will be little collectibles you can find during your runs, and they'll come in themed sets. Completing a full set will give your turtles permanent bonuses. I'm also planning to include little bits of flavor text for each Relic to help build out the world a bit more.
