Update 8/22: The issues with the currency have been greatly corrected. i have update my review to 5 stars. i also love you can create various “save files”, so if you share a phone with someone you can each have your own “progress” saved.—i have not experienced this app crashing, as others have mentioned. i’m on an iphone 13 and iOS version 26.5.2My problem with the game is that “rewind” costs way too many coins and the game does not give out coins generously enough. i have been on level 185 (one of the hard/question mark levels) for multiple days. Even the hint to tell me the two start colours doesn’t help. Since i have been stuck here for days i have no chance to get coins (to buy more hints or undos) other than from the daily “feed the cat” milk task, which doesn’t give enough coins to help.This game either needs to:1.) Lower the cost of hints/rewinds to 10 coins or less2.) Increase the coin rewards for completing levels (minimum tripling reward coins)3.) Add a “surrender/skip level” option if you fail a level 10 times and want to skip it. i’ve actually failed level 185 probably 50 times at this point, maybe more. i’m at the point of probably needing to delete the game. Or hope for an update to address the issues i mentioned. Game would be 5 stars if it weren’t for how scarce coins are vs how expensive hints (and vanity/cosmetic) items (like new flask shapes or sparkly fluids) are.

Fun game to begin with. But sooner or later you will be able to move no further. You gain coins for completing a level. 30 coins. Occasionally 50 coins. The problem is that the game constantly encourages you to spend the coins on “upgrades” like fancy potion jars or bubbling liquids. Don’t. You will need the coins to gain access to a beaker on some levels to help you complete a level. Access costs 100 for a single color level beaker but you can add to that for additional 100 coins. Undo costs 30 coins and hunts are 10. Thus completing the level for a net loss of 100 or even 200+ coins. Early levels are easy and will allow you to build up 1000+ coins very quickly but eventually you will need the beaker and you will be negative points per level completed. When you drop to less than 100 you cannot buy the beaker any more to help finish a level. There is a way to get 200 bonus coins on a timer but the timer only seems to run when playing so eventually you will reach a point where you’re stuck without the beaker because you don’t have enough points but can no longer get bonus coins because the timer to get bonus coins stops running leaving you at an impasse. You can restart the level but unless you’ve figured out the best way to finish without the beaker you will just keep restarting. I got to level 104 before this happened to me. I see other reviewers got to different levels before being effectively locked out. I get that the game developers probably have this set-up for players in a paid version of the game where that can buy coins for real money as an in-game purchase but they have been lazy in the arcade version in not changing the coin structure so you never run out of coins. Fun to start but eventually no fun when you can’t continue…..

EDIT as of the update: thanks for listening to feedback, devs. Now the 100 coin bonus cups you can purchase now persist if you restart the puzzle which does help a lot and it doesn’t feel as unforgiving when you get stuck on a puzzle. I would rate this higher if a lot of the issues with earning coins and spending them are fixed as I enjoy it as an ad free game. However, costs for the additional bottle do not persist between restarts and they cost 100 coins so there’s no incentive to keep playing when you only earn 30-50 coins each level. If you’re stuck, then you can’t earn money other than waiting or the cat timed event and you can only use it once which is frustrating because the balance between earning and spending currency is broken. Now i understand why people were willing to pay or watch ads to skip or earn coins however the translation to apple arcade’s ad free games does not work unless they balance the coin economy

I love this game and genuinely wish I could keep enjoying it, but situations like this completely ruin the experience for me.I reached Special Level 25 and was presented with a puzzle that appears impossible to solve without spending coins to unlock additional bottle space. This wasn’t the result of making a mistake or getting stuck halfway through. The level started this way, with no legal moves available.Even more frustrating, the game’s own hint suggested pouring a color that had no available destination. In other words, I would have to purchase additional bottle space just to follow the hint!What bothers me most is that the game also encourages players to spend their coins on cosmetic upgrades like bottle designs, backgrounds, and liquid colors. What happens if someone spends all their coins on those upgrades, only to encounter a level that requires coins to complete?I enjoy challenging puzzles, and I’m happy to spend time figuring out difficult solutions. But there’s a huge difference between a challenging puzzle and one that cannot be solved without spending resources. It makes me reluctant to continue playing or investing time in maintaining a winning streak when the game can seemingly put me in an unwinnable situation through no fault of my own.I really do love the gameplay, which makes this especially disappointing. I want to feel confident that every puzzle can be solved through logic and patience, not by having enough coins saved up.
