As for the resources you get, there are Coins to help you level up your Resolve (or stats), Lucky Dough to help craft gear in the oven, Crumble EXP to upgrade your Crumble Level (which is your overall player level that increases your Cookie level cap), and Cookie EXP to, well, level up your Cookies. The Sweet Blessing rewards, in essence, incentivise you to buy stuff, because you earn Blessing Points when you purchase items. You can, however, claim Sweet Blessing Daily Rewards every day to boost your Sweet Blessing Level, or collect Premium Rewards (only once per Level) too. The free ones can be claimed once per day, with the rewards depending on your current Sweet Blessing Level. These can help you earn Crystals and Blessing Points, which can be used to boost your Sweet Blessing Level.
