Hey Gamma!
I just recorded a long playtest video. I'll post it on the discord project when it's finished uploading. Here is my summary:
I played the game in a few sessions, and overall I enjoyed it. I loved the theme and the aesthetics! Cleaning up blood/mess was satisfying. I definitely struggled initially with the concepts of how everything fit together. I tried to figure it all out on my own, but ended up relying on the in game book (which was a very nice touch, by the way).
Overall I feel like the onboarding is going to be very crucial for this game. The easy arena felt very big for my first real "level." I feel like a series of very small levels that illustrate each concept would be ideal. The easy arena felt a bit daunting knowing how much I had to clean, and when I would make a mistake (knock over a bucket/use the mop when dirty) it felt bad just knowing how little progress I was making (I'm definitely not advocating to remove those penalties since they make sense, just provide a smaller play space to make the mistakes is all).
I also didn't quite get the synergies with the plants. I feel like I just didn't quite thread the needle on that. The only time I felt like I really needed to do something with them was to grow the sponges when I ran out. Other than that, I didn't really feel like I needed to do anything with them (again, maybe I was just being dense here).
Finally, I felt like some of the interactions were a bit clunky/unforgiving (hitboxes, etc). It feels like having to juggle all the items was a bit much, especially in the beginning (not knowing what you'd need, when you'd need, etc). Nothing that some tweaking won't smooth out.
Overall I like what you've made here, a fun concept that just needs some tightening up (The capsule art is great too) and a solid onboarding experience. Hopefully my playtest video ends up being helpful!
