Being required to perform repetitive and tedious tasks to advance.
"If you want to invest in your student(s) then you'll have to grind some stages (that might have limited tries) and hope to get the item required. If you didn't get it yet, spend money on pyroxene to recharge your energy/ticket or just wait for daily reset."
"the gameplay is repetitive by nature because you are making pizzas over and over, but the issue is when you are grinding just to achieve the next unlockable pizza topping"
"While the "grind" comes from playing the game, earning coins can be quite tedious. The player typically earns 5% of their score in coins once they crash. However, the player can earn double the coins by watching advertisements."
"Upgrading your cards can only be achieved by paying or grinding levels for currency."
"It's kinda a sandbox game, but it does have a campaign you use to get statues in order to battle against AI in turn-based, rock-paper-scissors-like combat, but you get statues by completing challenges / solving puzzles, which pretty much gives the player something to do besides aimlessly wandering around & trying things. The statues *do* level up though"
"The game is split into 'leagues', and sometimes you may be stuck on a league, having to play it a few times before becoming the champion, but at the same time, winning every league wouldn't be that fun, as the game wouldn't have any real challenge. I think the skill curve is not too steep and it's justified for what it is."
