Ooo, I love me a good boss-fight, and this delivered a pretty cool one! Love all of the different phases, attack patterns, and sense of escalation, especially the fun middle part where you're falling down. The use of reflection as your only means of attack was pretty cool, too: always a classic since it forces you to put yourself in harms way. Overall this was a great short and sweet experience, all wrapped together nicely with some cool music, neat visuals and style!
The downside for me was that the game was in a rather rough state. Some of the roughness are just nitpicks, like how the text boxes aren't layered on top properly, meaning their text can be occluded by foreground elements like trees, or how the world is so flat and the character is just kind of on top of everything instead of being in front or back of elements. An explanation of the controls would've been nice too, but I figured it out without much issue. But there were some more annoying aspects like how you can get caught on the wall instead of naturally sliding across it, or how some hitboxes and transitions would just glitch up or work improperly. It wasn't enough to stop me from enjoying it, though!
