Thank you Akusan :)
I had planned to make it longer, but due to the amount of time I had left, and my being aware that it would take longer to make the game as long and interesting as I would have liked, I decided to trim it down from a Metroid-like to an action-platformer.
Anyhow, I might either expand on this game for the upcoming Metroidvania Month game jam, or use a different character altogether :D
