The Genre Mix of Metroidvania nd Shoot em up doesnt work for me in this Game

The Armor System is stupid it just gives you temporary Hit Points

And the worst Part is the Card Skill System just let me pick my skills and use them with the mana.

A good combo of metroidvania, twin stick/bullet hell shooter card battler. It's a fun innovation on mixing multiple good genres.
By the end your player feels like a powerhouse, nice progression. Difficulty can be a little too varied but a decent challenge usually.

The Knight Witch is a nice twin-stick shooting Metroidvania. Expect bullet hell elements. Not too long, took me around 11 hours to 100% clear with all achievements.

This game controls fairly well, though there is some slight awkwardness always when games call for precision firing using control sticks/controllers. Unfortunately a mouse and keyboard control scheme, while sounding better on paper, ends up being more awkward than a controller in comparison as the camera can pan mid-fight causing a loss of precision that feels worse than controller in comparison. The game has an auto-aim mechanic that fires on the closest enemy when firing without designating a direction, at the cost of a slight DPS loss. My advice would be try to ignore your instinct to maximize damage: many of the smaller enemy types will go down faster with auto-aim, save aiming for bigger or more dangerous targets and focus on dodging.

The gameplay is typical twin-stick, move with left stick, aim with right. My experience with difficulty was that it was easy, then got appropriately challenging, just enough to make me wish I had a dodge, and then hey, there's the dodge move (it's the first major ability you unlock). After that things got slightly easier, before the game had an appropriate curve as the game went on. Combat is supplemented by a deck-building system, which I usually don't care for, but thankfully doesn't get too complex. You build a deck of a few cards, the size of which goes up as you increase the amount of mana you can spend to play cards. Cards can be one-time use attacks, defensive moves, summons, and weapons with limited duration. You get mana by hitting enemies (percent chance on hit to drop mana) and killing them.

The game's artstyle felt a little awkward when I was first getting into it, but it grew on me. Environments are particularly well drawn, and the character designs are cute for the most part. If I had any specific complaints, any time an NPC walks on-screen, it looks a bit jank, but depending on how you feel about the kind of thing, some people could find that charming too. Rayne (the player character) was given a lot of attention to her flight animation and it feels cool even if you aren't moving particularly fast.

The game's sound direction is solid. Sound effects felt satisfying, and the whole game aims for a more folksy music style on the whole, with more intense rock sections whenever you get into combat. I was a particular fan of the instrument shift into more industrial kinds of instruments in the water level while underwater. The game even capped off with a vocal version of the main theme of the game that was pretty nice. In my personal opinion, though, nothing particularly catchy that you would want to listen to outside of the game. Still, the game is complemented well in moment to moment gameplay by its soundtrack.

The story of this game was pretty good. No particular roller coaster moments or anything, but it did have some nice twists or two, some you'll probably see coming, and maybe some you won't. There's some nice backstory hidden in notes around the world that are unfortunately hard to find. I won't go into detail any more than that: the story isn't anything amazing, but it has its interesting points and at the very least shouldn't feel detrimental to the experience.

In conclusion, I'd say the Knight Witch is well worth the asking price, especially if you're a fan of twin-stick shooters and bullet hell. If you're not a fan of the genre, this game goes on sale pretty low (it's -80% off at the time of writing), so maybe consider giving it a try. It's a nice little romp to experience over the course of a week or so.

P.S.: I'll drop a couple of cheats here that I felt could've worked just as well as some options to toggle on and off by default.

Glass Rayne/One-HP Mode (useful if you're aiming to complete ambushes without getting hit): Blue-0, Green-1, Yellow-2, Purple-3
Show Damage Numbers (if you like that kind of thing): Purple-3, Yellow-2, Green-1, Blue-0
