Vibes are spectacular, art is great, but there are many little anti-QoL things that bring the experience down : /
This includes the bugs, but also the attack stopping you, the camera lagging behind you, and the floaty/way too fast character controls.
The intro section is also annoying - the text is too fast the first time through, and lingers for way too long afterwards. Later on, that's just me being stupid, but it took me a while to figure out I should attack the door on the floor to progress.
The layout of the levels has no direction, though that makes it feel quite interesting in a sense of being lost (positively). I'd say to make the layouts and individual rooms more memorable, and/or give a map, at least a simple square grid one.
I gave up when I got to the castle area, after the double jump, and fell out of the level's bounds. A quick restart button would've been nice here
6/10, excluding the bugs 8/10. Looking forward to a full release!
Edit: Forgot to mention, music is also really nice, and enemies look interesting but are hard to attack with just 3 whip directions. Then again, I never played the original castlevanias. That's probably me being bad at playing :p
