Pretty enjoyable game. Seems like the dev made the game free, but I would definitely be fine with paying "something" for this? (And wish I could)
Being a lone dev is hard, and clearly some work and time went into this game. And that is worth something. And I hope the dev isn't discouraged (Hopefully just on summer vacation)
My overall experience is fairly positive, but I'll mainly (constructively) discuss some weaknesses, since I think that is more meaningful as feedback. (Just what I feel, maybe I'm wrong about all of it)
First, I suspect, the greyscale, low-poly art style\vibe, while serving the story well, and being stylistically fine, combined with the zelda\metroidvania-style "start with nothing and gradually discover ways to expand the map" gameplay (which I LOVE), might result in the beginning coming off as overly barebones, and creating a weaker first impression than perhaps deserved.
(I might be explaining this poorly, but essentially, when first starting a new game, immediately, every aspect of the game is simplistic or barebones (on purpose), which is fine individually, but... it happens at the same time, before anything else is introduced. So it's hard to tell what the game will be, or rather "if" it will be more eventually. Making expectations start really low, so people either quit before they get far enough, or just colours the experience somewhat negatively for a while. If that makes sense. I think the UI might also contribute to this first impression, it leaves a bit to be desired, maybe in terms of feedback, but especially visually. But I get that UIs are not typically interesting to design haha)
I don't know how to solve this in a good way though. Maybe giving the player a sneak peak of what is to come (world\abilities\etc.) (Not everyone watches trailers)
The first unlock shows up very quickly, so does the next one. Which gives an idea what the game will be like. That's great! But it's not quite enough to set any grander expectations. So as a player, especially with the game being free, I was unsure if it was going to turn out that it was some bundled engine demo-level that had been enhanced and expanded on a bit before being published, as sometimes happens. Or if there was a full game with more down the line. Luckily it was the latter :)
Obviously, Metroid does it by starting you of with (near) every ability, and then taking it all away. I suspect that might undermine or diminish the original intent in this game though? Maybe? But, if so, there are definitely other ways of teasing things, visually, functionally or... falsely?
Is it on the level of something like Supraland or DEPO? Ofc not, but, in general I felt like the game evolved into something more later, it had some good puzzles, some interesting exploration that kept me wanting to explore, and there's a bunch of things to love here. (I think it also has some solid groundwork for something else in the future? If the dev wants to explore the possibility of that. Whether directly in this or in a new game of some sort.)
I do understand what some other reviews are saying, but...
Ultimately, despite some issues, I don't think there is anything really, really bad anywhere? It's all very fixable stuff IMO.
Also, some stuff to be aware off until there is an update:
There are a few bugs, mostly minor, but unfortunately one potentially gamebreaking one (You can despawn and permanently loose power cells it seems, and they are of very limited supply. If you think you lost one, backup your save, don't do like me and check again if you really did lose it... by losing another lol)
There is also one optional puzzle post-game, that I think might have bugged and become unsolvable for me? Involving some... hands. Or maybe I misunderstood\misremember. (It's been a little bit since I played since I've been hoping to figure out the remaining stuff without replaying, but no luck. Could definitely just be me being dumb though.)
