Wow that's a long reply, thank you VERY much. I really appreciate the feedback.
You are right, I'm missing a way to tell player that he lost hp and that slime attacks are a bit weird, 7 days is kinda short for me since I did all of the assets, that's also why I don't have any music and only 1 sound effect which is basic attack.
I'm really glad you figured out harder rooms (or read how it fits the theme), a lot of people missed it, I appreciate it :D
As for poison color, yeah people told me it's confusing but it was kinda too late to change haha. I first wanted to make enemies (like whole model)have purple-ish color or something, but didn't know how to do it in Godot with 3d models (in 2d it's just modulate, but I don;t know for 3d).
Also you are right about the shop and chances in general, you can get 3 spins after 1st level which is really bad, though again I didn't really have that much time, since I'm not really good with Blender, though this made me just a bit more confident in it xd.
I'm really glad you got to the boss, no one before commented on the boss. And I made a game harder since it's kinda short and I just like harder games haha (though I see why people say it's hard, especially for game jam and people just testing games).
Thank you SOOOO much for playing and making such a beautiful reply, means A LOT :D
Good luck in game jam :D
