Wow this was an amazing game! First the cutscene at the start was super cool and throughout the game I loved your art style and color palette. The music really fits the vibe of the game your going for and the SFX were pretty good!
I love the animation of the cutting heart and its super crisp and so polished it's insane for a game jam.
Now the combat at times for me did feel hard (but that might just be me) and I couldn't full screen so I kept clicking out of the game T_T. But the combat is well designed, and super satisfying. I love the screen shakes, enemy blood splatter and the SFX. The enemy variety is pretty good too. Now one feature I'd love to see is extra abilities cause that could go a long way, like multi shot, extra dash, etc.
I enjoyed this game a lot, superb entry in the game jam!
