Game fix / update wishlist. {For the devs should they return}

[MONSTERDROID]

I just wanted to make a post where I could contain all my thoughts on all the aspects of the game that could reasonably be improved or fixed so that if the devs return to this game it would be significantly easier for them to know what they could tackle to improve the user experience.

Bugs.

Quitting the singleplayer storymode & going to the settings menu causes framerate & sensitivity to return to a different value for some reason (from like 8 sensitivity to 5 & from like 144hz to 60hz options); I am unsure if this bug is purely cosmetic, but it is really easy to just change it back.

During the giant snowballs cutscene it is possible for the player to be attacked while they are off-screen.

The Jester enemies at the kingdom do not flicker when shot at, or seem unusually hard to kill.

Archers seem to be invincible for a few seconds when they begin to fire an arrow, some of them seem unusually hard to hit / damage as well (namely the mini-boss one)

Co op Bugs?

Continuing in arcade after a defeat causes player 2 to have to press start & re-select their character every time.

Sometime before the guy with the boulder is going to jump down in the firework stage it is possible to glitch the camera & make it go really far back.

Co op.

Add an option to adjust player 2's sensitivity apart from player 1.

An option to co op the story would be really cool.

An option to revive your friend (even if it just gave them one of your hearts) would be really cool.

Make Co op progress count towards achievements; we can unlock characters in Co op so I don't see why not.

General QoL.

Add projectile indicators for when a projectile is off-screen, there have been many times when me & my dad were hit by a projectile that came from off-screen.

Change the color of the attacks from the caterpillars in the mad hatter's stage (The blue on blue is incredibly hard to see until the mushrooms are destroyed).

Increase the damage over time or damage of the flamethrower to make it have more of a use (I literally harmed myself with the flamethrower because attacking the ninjas with it caused them to charge at me, whereas the SMG & Minigun both tear through them without aggro-ing them).

Make the flamethrower stream smaller (it is currently way to hard to see past it & the damage dealt for how much it obstructs the screen is just not really worth it).

Increase the max amount of ammo maybe (It feels like everything runs out really fast & can't be stockpiled for later either).

Increase the ammo availability (Ammo is hard to come by).

Increase heart availability (They seem to only ever show up with around 3 at most near the start of stages).

General wishes.

Add more noises for the SMG (Idk what the term is but there is a fancy technique to vary gun sounds)

Add a shotgun, add a shotgun, add a shotgun, thank you for coming to my talk.

4 PLAYER (You don't have to, but I'd love you for it if you did).

Make the soundtrack playable from steam (Supposedly only old game soundtracks have this issue, all new soundtracks are a part of the music section or whatever, I can look into this sometime to better explain this point) {Some examples of games that do this with their soundtracks are Portal 2, Ninjin Clash of Carrots, Gang Beasts, & Vampire Survivors}.
