Overall game is great, I really like the graphics (it pays a lot of attention to the detail, and there is SO MUCH different sprite all around the game), and I really like the idea of the game, yet for metroidvania it lacks movement. I really want to see different dashes, maybe grapping hook, and lots of different abilities. example of what I wish to see is, ability to buy some kind of item, that would allow you to dash (as secondary weapon), you would do damage, gain invincibility and use up 1 mana.(that is quite expensive)
Another thing I quite did not like was the linear gameplay. Make it less linear with a lot of different trees to go, and search. After all we have a map, so we can go back without any big problem. This would give it more adventure style, and it would make me more happy to explore the game.
Also, I hope you will find use for shards (probably make a shop)
And the most important thing, The combat system is not good. I want to be able to use my weaponry in more directions. I don't know how do you make it work, yet I want to be able to choose direction of attack for all of the weapons. This would make the battle system less frustrating, yet extremely more fun.
Last thing I want to mention, It quite lacks story, and I would loved to see the storyline of the game go. If you are able, add some fun details and stuff, and this game will become INSANE.
I really like the project, and if I will be able to support it, I might try. I want to see this game become a winner of indie game 2021, or 2022. It would be really fun to see this game become on of the best.
I know it might take a lot of work, and result in burnout, but it extremely worth it.
