Interesting game, but I didn't have the patience to play for too long sadly.
Aesthetics are pretty viby, they give me the feeling of "old PC disk" games, despite me never actually living that era. Not sure if that was the intention, but it surely work for that lol. I also always appreciate me some lore :)
Fall damage on platformers are always a surprise, but they can definitelly work. Altought, the way you implemented it here is a little too much, since you can literally die by jumping out of a small hill instead of walking out of it (Granted, this way it generated some hylarious looking deaths, so that's a plus on my book). The collision with the floor also fely slippy, the player ends up sliding down from the platforms if they hit it on a corner, and I assume that happens because the player hitbox is a circle. In this case I'd say it's important to add a failsafe where the player would always be put on top of the platforms when hitting them from a corner, specially so for a game with fall damage, since most of the times I fell to my death didn't actually feel like my fault.
The control scheme is just really weird tho. I already don't like jumping with the spacebar, but that I understand it's personal preference, so I can live with it, but now using G and H on a game that moves with the arrow keys is just wrong honestly, not to mention having to make your hands travel all the way to Enter for every dialogue that pops up is also quite the chore. Ideally, you should be able to close the pop us with either the shooting or jumping button, and the gravity boots and healing runes should be somewhere near X like C and V, or even change the gravity boots to be activated if pressing up while on the air, anything is better than a key that is on the middle of the keyboard that you need to either take your hands out of the other inputs or stretch your fingers on really weird ways.
Also missed some more feedback for receiving damage, but in this case it didn't feel like as big as an issue as it did on other entries tbh. Either way, I only played up until getting the gravity boots, since everytime I died after that I would respawn with a buggy pop up message that I needed to keep spamming Enter to get rid of, plus being poop sniped by the big sparrow that lives there while saved with what was essentially 1 hp. And of course, to get out of there I would have to use the item that is triggered with G.
Anyway, here's a gameplay vid if you wanna see it, it was actually fun enought to play that little beggining btw, I just stopped because I really couldn't dig the control scheme
(Also, I actually played this game a few hours ago, but my laptop's battery died before I could finish writing my comment, so those toughts aren't super fresh on my mind anymore, so I might have forgotten to mention something else)
Edit: I just opened the game up again to confirm the controls, and I think I discovered a secret forbidden move by pressing V x)
