I'm really mixed on this game. I followed it because it was listed as a Metroidvania, so keep that in mind as I make my comments.
1. Graphics and sound are fine. I had no issues with the art style or sound. It's a 2D platformer, and it felt modern enough, even with stylized graphics.
2. Controls: overall the controls felt really good. I was glad to see controller support for my preferred controller, and it also allowed customization of controls if needed.
3. Difficulty. There were some strange difficulty spikes at certain points, sometimes in terms of number of enemies in a crowded space, and some where very long platforming sections required you to start over if you made one mistake. There is also a strange mechanic where killing enemies produces "chaos" orbs which you collect, and as you collect more orbs, the enemies become more difficult. There is really only one reason to collect Chaos, and you can work around it by buying a potion which gives you max chaos, which is what I suggest for the areas where you actually need it. Otherwise, the enemies are needlessly difficult, and it just doesn't make much sense. Maybe this was supposed to be fleshed out into something more, but the Dev team didn't really make anything unique or interesting out of this mechanic. I was playing on the 2nd difficulty out of 4, so it could be easier by one level for someone wanting less challenge.
4. There isn't much depth. The economy is basically collecting shards or an occasional temporary power up. What do you use the shards for? Buying more temporary power ups. There are 3 unique power ups throughout the game. One of them is an extra life point, which is definitely worth purchasing. One is something I thought would be plot related but does absolutely nothing at all except earn you an achievement. The last one is for fun and gives you a funny plot scene.
5. There is no other way to gain gear, level up, or advance your character outside of the game giving you abilities that you need a certain points to progress. There are some optional abilities you can earn through special "bells" that can be activated when you are at maximum chaos level, but again, the temporary power up to max your chaos will help you achieve that prerequisite. The abilities you gain from the "bell" challenges are nice, but not necessary to complete the game.
6. The story is about what I'd expect it to be for a game of this style. It's not the best story you've ever experienced, but you wouldn't expect that in a Metroidvania or platformer anyway.
7. Length: The game is rather short. Some other reviews mentioned that the dev team was swapped up halfway through game development, so maybe that's why we were left with a shorter game, but if you want something that will last 50+ hours, this is NOT your game. I beat it with 16 hours on my save file, but that includes a ton of AFK time as well, so I'm not sure what the real game time was.
8. Polish. The game was bug free and looked great for me. I know some people mentioned bugs in the game or graphical glitches, but I didn't expect any of that. I was actually quite impressed with how smooth the gameplay was.
9. Finally, I was following this game forever because it looked to be a promising Metroidvania, and it's not one at all. It's just a 2D platformer, and I can see that the Metroidvania tag has been removed from the game. It's just a 2D platformer, so I was let down because that's not what I was expecting from when the game was first announced to when it was first released. That's probably my fault for not following the development of the game closely enough.

Verdict: wait for a sale or to see if the devs release an expansion or content pack to add more value to the game. Otherwise, the game doesn't contain enough content to be worth it. On the flip side, it's only $15, so maybe it's still worth it at that price point. I wish I could give this game a neutral rating, and I can't, so I'm going to give it a thumbs up with the hope that they release additional content through a future patch.

great game i enjoyed playing it i love how easy the game concept is lore etc.. the pixel art is so vibrant and how colourful it is

I'd tell you how the game played if it could survive starting a game without crashing.
