Just played for a bit. I love how cute the characters are.
Controls are for the most part intuitive but I do appreciate on-screen prompts as well. Unfortunately, they're hard to read as yoiu're immediately attack and they fade away quickly. I suggest having mechanics come up one at a time, ie tell your player to use WASD to move without any enemies spawning, tell them to click to attack and give them time to read it (or require they hit the dummy a couple times) before enemies come in.
I saw "Press M for" something but didn't get a chance to see what that was.
What seemed like game overs were just end of days, so I wasn't sure what the objectives were (unless it was to just survive long). I started out close to the flame because I thought I was suppose to guard it, but then realized the enemies will follow me away from there.
On the enemy behavior, all I could see was them following and attacking, so there wasn't any strategy and trading hits seems inevitable. For enemies that require more strategy, I suggest visual feedback of attack windups and cooldowns, letting players know if they need to make distance, close distance, etc.
