Very short and feels more like a proof of concept than an actual game. I can see a lot of ideas, and I would urge you to play more similar games (or at the very least watch people play similar games more), like, action adventure platformers (metroidvanias, essentially) because you're hitting a lot of the tropes but there's also a lot more you can do to improve execution-wise. The animation's a little lacking, but that's forgivable if you were trying to manage everything, in which case, really, getting gameplay right is more important. But even then, like, the attack hitboxes look too close to the character so you're literally at almost 0 range when you attack not giving any real options for dodging in an out of attacks. And hits don't provide any visual or auditory feedback, so I can't really tell if my attacks are landing because they both don't flinch or get knocked back, and there's no hit/damage sfx; and at the same time I don't know I'm getting hit other than when I look up at what is essentially a health bar.
I'm not trying to destroy your efforts here. I don't know what your circumstances were. I just feel the execution leaves a lot to be desired, and that it comes from a lack of experience. I say this with a 100% genuine desire to see you do better in the future. Good luck out there o7
