Enjoying the game but a couple suggestions,
1:The Lucky Charm - should be sold in the Hidden shop for those that goofed up the chance to get it.
2: Hidden shop should have an upgrade to lower the amount of fights on normal Monsters it takes to get tot he next level. First level would lower it to 9 per, then 8 ect to a max of 5 Mobs per level. These upgrades should be fairly expensive. But will speed up the very late game grind.
3: Hidden Gems shop should have an option to reset upgrades. Reset on both the Green and Hidden Gemshop/Ascension shop should be a flat fee for resetting spent gems and not a % rate. 60% makes it so no one will ever use as you just lost 40% of your progress. The current system is way to unforgiving for making changes.
Just my thoughts. Love the game. Pumped to see how it progresses.
