“I'm not gonna pretend I picked this up for any reason other than pure, unfiltered nostalgia hitting me like a truck. Saw the thumbnail, heard the music in my head and my wallet was already open. And you know what? It…”
“It's super fun and entertaining. Definitely keeps you busy and there's lots of cute fish and creatures to help you. I've played this game since I was a kid, I definitely recommend.”

“It's on sale and that would be a steal. I didn't mind purchasing at full price ($5). Worth it in of just its existence. Crazy this game is the foundation of the internet and it is quite forgotten.”
“FISHY, WAKE UP, WAKE UP FISHY! on CachyOs had to use proton 8 so it would accept my text inputs. great game! lots of fun, got it on sale for 99 cents (CAD)”
“I paid 99c for this game. I've already played for 6 hours and still have the bonus and timed levels to beat. This was definitely worth the price. It's a classic clicker game. This may be difficult to play for anyone…”

“endless fun, cute graphics, silly and can be intense (for new/young gamers!)”
“I love this game. The mechanics are simple to understand yet there are so many ways to play. I enjoyed playing it a lot. The final tanks in the adventure mode were challenging but very rewarding. Guppy 👍 Thank you.”

“Awesome game. I've been a fan of Pop-Cap games since the early days of the XBox 360 Live Arcade, and the plethora of high quality, addictive and smooth playing micro games that they released during that time period.…”
