I enjoyed this little simple game, all 3 levels were pretty fun, and the objective was clear and simple.
However, level 3 is a nightmare since you can't jump back up so if you've missed a butterfly you'll have to die to respawn or restart, so it made the game a bit annoying. would have loved to see more levels and maybe have the cameras zoom in less it was hard to tell where I was jumping so 50% of the time I would just fall into the void xD
Don't get me wrong this is a really fun game, I wanted to keep playing but sadly only 3 levels I would assume lack of time, but you've done good, it has a settings menu, and a main menu and it works.
the downloadable / exe had this bug where all the buttons/starter menu would be broken but the WebGL / HTML version works just fine. overall a great game, good job!
