Great game! Congratulations on completing your first game jam. I hope you had a great time and will participate in many more. Our two games are similar in many ways. The movement is smoother in your game and I prefer your eating sound effect. I was very surprised when touching another axolotl lead to Game Over in your game since it is the goal of mine.  One thing you might want to look into: When I played the game in my browser (Google Chrome), pressing up and down didn't just cause the axolotl to swim up and down, it caused the whole game page to move up and down. As a result, the whole game window could eventually go off screen.
