Very high quality platformer!
Gameplay wise this game great! The platformer mechanics took a while for me to understand, but once I got the hang of it the game was really enjoyable! I really enjoyed the varied level obstacles, and I thought the shark gimmick in the final section was really well done. The main critique is simply just the fact the mechanics are not well introduced and could deter some people from playing the game, and causing them to quit early. If you fix that up the gameplay would be fantastic.
Visually the game pretty solid, with one major issue. Each individual aspect of the game looked great, but they looked a bit off when combined together. For example the crab stands out a lot from the turtle. If the art style of each aspect was more consistent then the game would look far better.
The audio was a bit of a mixed bag, as there was some very bad sound balancing with some of the sound effects, but the music was pretty good!
The usage of the theme was fairly good! I thought the story of the game was fairly simple but cute, and it used the theme very well!
Overall, there only a few issues with this game, but overall this game is still excellent!
