Great little game. I discovered it through the YouTube vid I/O made, came because I was curious to try it, and, honestly, the main reason I'm finding myself booting up the game now is for the music... The soundtrack is phenomenal.
Regarding the gameplay itself, here's my experience in case it is useful for the development (this is my first time posting on itch, I'm assuming this is where i can give feedback, but, if not, I can move this!):
1. Positive: The indirect way the game design teaches you about the mechanics of the game I think was done really well. I picked up the game after watching the first video breaking down the design philosophy behind the game, and I was still surprised at how effective the level design was at teaching the movement mechanics;
2. Negative: That said, there was one mechanic that I really struggled with - it took me a long time to figure out how wall jumping worked exactly... Because of this, I actually found Level Two significantly harder than Level Three. I think the fact that it's something you can do the game introduces effortlessly, I did my first wall jump without giving it a second thought. But it took me a long time to understand that when you first wall jump there's a brief moment where your character sticks to the wall, giving your fingers time to change the inputted direction... I did eventually figure it out with trial and error, but i found it very frustrating. Don't know if anything can be done about it, but wanted to mention it;
3. Bugs: there are also two bugs I ran into. The major one is that my sliding is inconsistent... It doesn't feel like it always registers. I don't know if it's user error, or something to do with my keyboard, or something else... Its just, since this is a game about movement, not being able to control movement smoothly stands out... I can try to capture some video footage if it's helpful. Secondly, as with DarkAtrium, the level selection menu, the settings menu, and also the image with the control buttons at the start of level one all clip outside the edges of my screen (playing on a 2k monitor in case that matters). It honestly doesn't impact the gameplay experience at all, just mentioning it.
4. Suggestions: lastly, a suggestion: i think it would be really cool, and helpful, if there's a visual way to show the user when the dash has been used up, and when it can be used, like in Celeste.
Excited to see where this game goes!
