Comments on Unit 404 for Android

★★★★★ Will _ · Oct 26, 2021
Very entertaining up to the 60s levels then it gets challenging, but sooo addictive. Love this game.
★★★★☆ Andrey Fomchenko · Feb 24, 2022
Graphics are very good. Levels are not as rewarding to complete as they are for example in Snakebird or Oriental Express. There's no ahaa moment, more like trial and error. And no undo button as mentioned by others is very frustrating. Game design and built quality is very solid though, so 4 stars.
★★★★★ Blair Davis · Jun 3, 2022
What a great and challenging puzzle game. I have Enjoyed all the games you've made so far as well, hope for more games like it.
★☆☆☆☆ Pierre Bezuidenhout · Aug 27, 2025
2 ads before the game even started, another after every level? Nope. Wrong way to monetize for sure.
★☆☆☆☆ Taylor Phillip · Jul 24, 2025
ads ads ads had to watch 3 ads before I could even play the first level and 10 seconds later another 2 ads. Worthless
★☆☆☆☆ Jay Wendt · May 5, 2025
Many ads, even with Play Pass. First ad was before the first level even started.
