This game feels so well made. I really like sprites that you made except for the background which hurts my eyes a little. The music is also pretty nice. I definitely enjoyed the gameplay. It hit me right in my Fire Boy and Water Girl nostalgia. I was really surprised by the amount of well designed levels there were, so a suggestion I have is to add a level selection screen. Also I beat all the levels in 4:18. Overall this was very fun, good job!
