A decent start.
Overall the combat and combos feel good and is the strongest part of the game, though enemies could do with either more telegraphing on attacks or better hit box detection on the player's side. I kept dying to enemies walking into me and I couldn't hit them easily. Or maybe a defensive option such as a dash or block, just a suggestion.
While I know the game was likely designed for gamepad not keyboard, overall I found myself fighting with the controls more than anything. Which greatly lowered my enjoyment.
I would recommend combining actions into fewer buttons. Especially for movement where simpler is always better.
For example hold 'down' and press 'jump' to drop through a ledge. On thin ledges when you have the upgrade just hold 'down' to start hanging from it and then hold 'down' and press jump to drop from the ledge or press 'up' to climb back up. That sort of thing, also I'd recommend going with auto grabbing ledges and vines as you jump into them, or least if you are holding up. Basically I feel all the climbing stuff could be smoothed out a bit more if moved away from its own separate button and tied to regular movement and jumping controls.
I can understand having crouch be its own button especially for controller, but I'd recommend seeing how it feels by also having crouch on 'down'. For controller you could try seeing how crawling feels if it works by tilting the stick diagonally downward.
All of this is just fuel for thought because right now the controls feel really bad on keyboard as I constantly have to shift my hand, but that may be a me problem.
I had a quick look at your dev log and noticed you were struggling with the exploration part of things as your game is more focused on combat. Personally I think your game would do well by doubling down on the combat side of things first, even if that makes it more of a fighter brawler with exploration elements as a side.
Have you heard of the game Guacamelee!, that too is a metroidvania with a more combat oriented game flow and heavy focus on combos, might be worth looking into.
Anyway keep up with the good work.
