All mistakes, code, and design by Frans van Bellen
This line made me chuckle.
Overall, I really enjoyed the game and can see a very solid base that needs a few improvements. Clearly, this is a genre you are refining rather than learning. I want to see more roguelikes like yours out there. So, allow me to play co-designer, despite how unwelcome it may be ;)
The game looks beautiful. It's very artistic. UI looks great. Everything is nice and clear too. There's zero confusion. Even a casual gamer would know what to do!
I really liked the menu system, it removes the need for memorising complex controls, which make so many roguelikes impenetrable. Yet it doesn't reduce the game play down by cutting things out.
It might be nice to give the player more info about the attacks. I can see how much they cost, but not the amount of damage they do, for example.
You could also cancel the menu using right click or just when clicking elsewhere, as a convenient touch.
I found it hard to feel like John Wick when my only attack is a punch that only does 2 damage, whereas the first enemy does 3. And early on, I'm facing 3 of them simultaneously. This just makes the player feel weak and not like some badass.
For example, what should my play be here:
I'm just gonna lose, surely?
Sound effects would be a nice addition.
As a minor issue, the music was very repetitive and distorted, even at low volumes. I had to turn it off. It's an easy thing to fix.
