I think the concept was very interesting! Switching around who was in front to tank damage felt like I had to make choices on who to swap out a lot, especially near the end when stuff got a lot tougher. There seemed to be a lot of inconsistency of when and where I could use certain abilities - I don't know if I had just missed some sort of pattern or not, but I think some clearer indication would have helped a lot. It looked like there are some tile/grid indicators in one of the screenshots, but not in the game? I don't know why it got changed, but something along those lines would have helped my perception of the field a lot more.
It was definitely unfortunate that there were quite a few abilities that would sometimes crash the game - definitely felt averse to using them (especially in the longer fights) due to the possibility of a game crash, and losing out on those extra tactical options ended up making Venom Kiss irrelevant up until enemies were right next to her.
The art was very nice, and I liked the designs for the main characters a lot. The enemies were also pretty uniquely themed and felt very cool and intimidating! I enjoyed the music quite a bit - I let the opening theme play all the way through before I started since it grabbed me super early on. The voice actress also did a great job differentiating each of the character's energies and tones from each other.
