First off, thanks for playing!
About the combat - I was going for a more castlevania style, but it probably didn't work as well as I'd hoped due to the lack of weapon choice. I'd actually put a lot of effort into an evasive dash move, but unfortunately I ran out of time to code in the area where you would find that powerup. I'm really happy you enjoyed the atmosphere of the game - Thanks for the comparison to Metroid /Metroid Fusion!
I also agree that the hitboxes are too big, I'll have to fine tune them slightly.
