Dove into it without reading the instructions and swam till being blasted X5 when I've finally reached the end.
Going at it I didn't feel tired to go again, which I'll attribute to the procedural design, fast pace, and difficulty level.
The audio was a good choice. The track complementing the pace and the dolphins the immersion.
Solid game except for when crushing into a wall and getting ungracefully stuck for a while.
I had fun so you did a great job! :D
