### 1/5 — Confusing

*2026-08-18*

You can fulfill all obvious parts of the puzzle, but the puzzle won’t be “solved”. Almost like there are multiple solutions and the game is only looking for one.

### 1/5 — Ads before and after you play

*2024-12-30*

Ads to refill play tokens, ads autoroll after every game. I’m shocked you don’t have to watch an ad to install the app.

**Developer response:** Hey, thanks for your feedback! I totally understand that ads can be frustrating, but just to clarify—there isn’t an ad after every game. Interstitial ads actually have a cooldown of several days. Are you using the latest version and closing the ads properly?

On a side note, ads help keep Tawa running, as the app currently costs more to maintain than it earns. Without them, there wouldn’t be a Tawa at all! We always try to keep the balance fair, but I appreciate your thoughts and will take them into account. Thanks for giving the game a try! 😊

### 5/5 — Simply the best Akari app!

*2024-12-03*

Mathematician here, I absolutely love logic and number puzzles. Sudoku was my favorite for a long time until I discovered Akari! Now that Nikoli no longer has an app, this one is a must! Thank you!

### 3/5 — Fun type of puzzle… all stuck behind a pay wall/ads

*2024-10-16*

At least make maps for free in the first couple of chapters and then i different place to purchase more maps. Kinda crazy, makes it less fun that it’s $2… A PACK

**Developer response:** Hey omdave83, not sure if I get you right, but you immediately get 60 pack games for free + 365 free Daily games + 52 ultra difficulty Weekly games per year. Isn't that a lot, how quickly are you solving the games if you don't have several hours, if not days of free fun with them? :D

### 5/5 — Very Interesting Game!

*2024-10-15*

I just downloaded this game yesterday and honestly I was very surprised at how well made it is! The beginner tips are very thorough, and it definitely makes for an interesting way to pass the time!

One little suggestion I do have is about the highlights. Would it be possible to make it such that you can highlight a cell with two colors at once? For example, if you want to put both blue and green in a cell, would it be possible to show both colors? It would make it a lot more convenient for marking chains.

Other than that, this is a great game! I’m surprised it hasn’t gotten more attention. Keep up the good work! :)

**Developer response:** Hey HalfKite, happy to hear that you enjoy playing Akari! Thanks for your suggestion with the highlighting. The next time I have some time I will think about the best way to implement something like this. I don't want to promise you anything, but at first glance it sounds the multi-color highlighting could be very useful :)
