This was a really fun and diverse experience!
The design of this game was very well made, and the story felt complete. Introducing the game's main objective of having to reach the pink axolotl at the end of the first level made it clear that the game had a defined ending. The transition between the first and second levels was very smooth, with the shark eating you and then becoming the new enemy in the second level. The goals of each level were always obvious without needing any tutorials or hints. Each level followed a familiar pattern with spikes and bubble currents, but as the game progressed, new and unique challenges were added, which kept the game interesting.
The variety of different enemies and their unique properties was impressive. The small warning from the electric eels was subtle but noticeable enough that they never surprised with their attack. The third level was the coolest, in my opinion. The camera zooming out, the music changing, and finally revealing the big whale were all very dramatic. The final boss was fun and well-made; it wasn't too easy but not too difficult, which was good.
I did run into some bugs, but they didn't ruin the experience. The first one was that the small squids sometimes got stuck in the spikes and other enemies. The second was that a shark could push the player through the wall. Restarting the level fixed this, but it was possible to finish the level inside the walls by finding the end.
Overall, the game felt polished and it was really fun to play!
