Congratulations to your first game! It is fun to play! I really liked the simplistic graphics. I am not so sure about the music :). In general I like it, but it is maybe a bit too noisy for this game. The random placement of the hearts could be also improved, so that they are not spawned so close to a tentacle that you cannot reach it, otherwise it is less skill based and more random to reach a high score.
Hope you had fun creating your first game and we hopefully see you again next year!
