This is a very polished game! I love the minimal artstyle and the music, the transition from the main menu to the game is a great first impression. You've got great game feel with excellent visual effects, sounds, screenshake, a good difficulty curve with optional levels, and I appreciate the small detail that light is faster than sound!
Two pieces of feedback: I think the one way platforms could use a little more clarity. I can see the one row of solid pixels for the 'solid' side and the side you pass through skips every other pixel, but I think which side is which could be made more clear. I also got stuck in the environment a couple times with the wave, the first time being the very first feather. I got stuck in the ground and needed to restart. Screenshot below.
Awesome job!
thanks for this really nice feedback! Artist here, so very glad you enjoyed all of the graphics, I spent a lot of time making it look nice :D The one way platforms is definitely something that people have talked about, and I do see how it could be difficult to notice. We will definitely fix that in our next update. As for the ground stuff, it is a known bug that we have been trying desperately to fix since early in development, but were only able to mitigate it a little bit. Hopefully we can find a way to fix it fully! thanks again for playing :DD
