Radical fishing but it's made for mobile.
I played this on the PC, and I think I would've had more fun if I did so on m phone. That said, I did have fun and enjoyed the game.
A few suggestions: it would be nice if the upgrade page didn't pop up every time, intead there should be a button for me to open that. Also, it would be cool if there was something showing me how far I am from the surface when I'm going up, like there is when going down (when going down that is useless, but would be pretty useful when going up).
Guess I'll try playing this on the phone later...
P.S.: I noticed that there are achievements, but they directed me to a completely different page, why not make them NG achievements as well?
