Hello, I managed to reach the boss on about my third try, and gave it two more attempts after that, but haven't won yet. The controls are very smooth, and the art style is quite cohesive—though speaking as a layperson, while it's minimalist, it does feel a bit lacking in distinctiveness. That said, it's definitely one of the finer games I've come across. However, since I have very limited experience with games in this genre (I've only beaten the first boss in Blasphemous 2, and that's about it.Later on I got lost in the map), I'm not entirely sure—would it be worth taking another look at the attack feel and platform height settings? The boss's HP also seems a bit on the high side. I think the enemy design is quite straightforward—I just didn't expect the map to be this limited.Ultimately, whether to continue development is entirely up to you, but you might want to consider designing some characters with stronger promotional appeal.By the way, I didn't realize that meter was actually a potion charge indicator—I thought it showed the wave progress.
You're also welcome to try out my games—they haven't been polished to that extent, and I'm also looking for feedback from all around.
