Rough around the edges but still has charm to it
the graphics didn't feel all too NES-like, but were enjoyable on their own
There was one part during the game that I needed to do a blind drop to a platform below (ended up gambling on a long jump instead and got spiked) so I'd just be aware of the camera and what you can and can't see while playtesting. Always try and approach it from a new player's perspective, if you only drop down because you know the platforms there having built the level, it's not quite ready yet.
Not the long one onto the platform with gems to guide btw, that one was fine, it was earlier on.
Otherwise the game felt pretty good, The smiley enemy looked a bit like a collectable to me, where the grimoire? later on did not. (well it kinda did but in the context of the smiley enemy I did swipe at it first to check xP)
Some audio would go a long way in improving the game feel.
