Nicely done game. I did get stuck pretty early on — right after picking up the jetpack; I found I could dash up, but still couldn't get from the first platform to the second one to get out of the pit. So, that was the end of the game for me; not sure if there is meant to be more after that or not.
But the animation, graphics, and sound were all pretty polished, and it has a nice Metroidvania feel to it; seems like it could be the start of a very engaging game!
