Managed to beat it, had a blast! Aesthetic was simple but effective for a game like this. Really smooth controls and plenty of attack visual cues made it feel like it was my fault when I failed, it was just hard enough to keep me going. Feels like I cheesed the cube boss tho by simply staying hooked to a far away pillar and going in circles, but still managed to be challenging and fun.
Hat's off to you, hope to see you at the Boss Rush Jam next year as you're clearly good at it!
