The use of medieval art for your assets is such a genuinely good idea I'm sad I didn't think of it hahaha. I really liked everything in this, it all worked together really well, and I don't think I could give any feedback that hasn't already been given on improvements. I'm also shocked I haven't come across another game referencing the black death.

Didn't expect to be motivated to work on my own project by Medieval Long Boi the game, but here we are! Great job making this especially for a first time in an entirely new engine!

I'm no big brain dev, but thought I'd leave a bit of feedback. Hopefully it'll be of some use to you! 

Like many others have said in the comments below, the artstyle for the characters is really interesting and the music choices are fitting! The font fits as well, though it can be a bit hard to read from time to time.

I do appreciate how you can basically use mouse only if you wish to (not saying you need to stick with that though, just thought it was interesting!).

A suggestion would be to have an indicator of how large Muriceps' attack is! I was pleasantly surprised with how generous the hitbox was as I thought the attack range would be quite small, considering it's like a punch. Maybe something similar for the rats too? Another thing to point out is that the punch noise might be a liiiiittle too loud.

Another suggestion would be perhaps for a run button! Chasing rats can take quite some time, and especially in that last really big dungeon, when you have 1 to 2 rats left, it can take quite a bit to traverse through the rooms.

Whilst I understand you'll tune the references down if you continue to work in this game, in an overall the humor was nice!

I also played the nefarious mode, and the rats chase you when you get too close, which was a nice surprise! One thing I'll point is that the distance they can damage you from seems to be quite far. There were times I'd kill a rat and receive damage. I do appreciate that you gave +2 lives after the first wave of rats in the last dungeon room, though. Also, extra modes with differences between them? That's hard stuff to do! Good job!

This is really good work, especially considering it was your first experience with Godot! Can't imagine how scary it'd feel to go into a gamejam using an engine I don't have any experience with. 

Also, yes. I'm a fan of the battlecry button. I like it. Quite a bit.

Well done! It'll be interesting to see what you do with the experience that you've gained making this game! Good work!

I played the whole story mode but i ended up loving Nefarious Mode because the rats actually chase you in that one. I wished the levels starts out with more rats and they make more babies but i think that it could potentially be stressful if there is that one rat that you couldn't find.

But the rat idea is super interesting--an ever growing rat swarm that you had to hunt slowly or they'll grow out of control.
the story is....hmm...I couldn't really get into it--someone said that there are alot of quote and reference from Thor so I guess its too deep for me to understand. like the...person inside that square...bathtub? idk what that is supposed to be.

the art style have good potential. im imagining a cuphead level visual fidelity but in the old medieval art style. :>

Loved the art style and the quote from Thor. Super awesome game since it's your first experience with Godot.

Love the art and music.  Does the game have a win state?  I think I killed all the rats, but nothing happened.

I really Love the art and animation in this game. The way you've given life to medieval art is wonderful. Though, the gameplay itself is quite bare and the sound effects seem to gave come from Space invaders. The Writing is appropriate, but with the fancy typographyit's very hard to read. I would love to see a polished version of this though.

Simple, enjoyable game. Really liked the artstyle. Great job!
