The web build does not do this game justice, I think downloading this game is definitely the way to go. I'm really impressed by how beautiful the game is, the art and the soundtrack is well made, and somewhat reminds me of hollow knight. The combination of rythm and platforming is very creative, having to time your movement to the beat is a smart idea. The addition to increase the timing window at the settings was really nice, more games should not be shy to add assist options in their settings.
Now I want to talk about some unintended ways of playing and also a bug, and it all relates to button mashing. I found myself being able to pretty much fly horizontally by just mashing dash button, misinputing the dash does give you a shorter length, but it still suspends you in the air, and because of button mashing you can get some "correct" timing, which does gain you a bit of distance. The same thing happens with the jump orbs, anytime I get close to them I can just mash the jump key, of course it doesn't always work, but it works well enough. The bug that I encountered was when I was absorbing the circadian energy, if i were to mash "k" then the screen shake that happens at the start would intensify and prolonged (which was funny the first time i encountered it, but a bug nonetheless).
Ultimately, it's impressive by how much work and innovation you've all put into the game in such a short time. I can definitely see a lot of love and care has been put into the game, great job!
