Not a bad game, but I thought this game was too hard to be considered a "stress-relieving, relaxing game" like you said honestly haha. I like the visuals effects a lot, but I thought the sprites was a bit too similar and hinders the gameplay.
The music and sound effects were nice, but I think it would have been much nicer to not have the music starts from the beginning every time you die and just let it keep playing since in my experience you lose very fast and very often.
Overall fun, but I think a little more polish could go a long way :)
