I was just going through some of my videos, and noticed that your Boss Battle got cut off the end of my playthrough.  Well, I've posted it now of you wanna see:

I think there are some obvious points to highlight; the visual and sound aspects are great, although perhaps the boss music is a bit loud compared to the rest. The gameplay is excellent; I enjoyed the feel of the combat and the movements in general. But something I would like to highlight is the level design, which I think is excellent. At no point did I feel lost, but I also didn't feel like the game was holding my hand; it definitely has that Metroidvania element that invites you to explore and constantly change routes until you find the necessary upgrade, and I thought you executed this part greatly.

My only problem is the menu when dying. Several times I was about to close the game because the menu responds immediately. And while fighting the boss, it finally happened :(

I was playing so frantically that I didn't realize while I was pressing buttons like crazy and closed the game when I died. I can simply suggest leaving the Resume and Back to Menu buttons. Or maybe have a saving system, haha.

Anyway, I've almost rated this game perfect; I think I'll try it again soon.

Everything's very pretty and cohesive in the visuals and audio.
The jump feels very smooth, and the attacking feels pretty good.
The only thing that felt a bit off was blocks moving sideways which were a bit slippy.
Great entry!

EDIT:  I just remembered, the Left Right input doesn't reset on room entry, so that's why I walked off edges a couple of times.

Very nice visuals the audio is very good.

I like the animation, scene, background, color scheme, enemy design, a good use of post-processing

The control is slippery at some platforms and slopes, and the knockback from an attack is too high.

The locked door before the dash upgrade and the lever are fine for putting far apart but it's less visually related, if the lever has the same color or has the same symbol should be better. because when I switch the lever I have no idea what happens until I recheck the dash upgrade room.

Overall the game looks nice and polished well done!
