I did it, I reached level 10! The final boss for me was the dude in the water, took me a while to find the tool to beat him, but it was a very satisfying final boss, I even felt like he had the longest explosion (fitting of the great feat of beating him).
Gameplay-wise it's all very crisp, I always felt completely in control, and when the enemy got a hit in it never felt unfair, it was just me misreading the pattern. I played with a controller and I have no problems there. I think the only thing I'd mention is that during the tutorial, it wasn't clear to me which button in the UI image was supposed to be the lock-on button (pressing the right analog stick if I'm not suffering from turboalzheimer).
The one thing I'd like to see more of is the status effect system, I saw that both I and the unfortunate enemy I pushed into the water against his will were dripping wet, but what exactly did that cause? Or did I miss a sign that explained that? I think I got what bleeding did though.
Either way, this is shaping up to be a super fun exploration game!
