Incredible game man! As a Celeste fan, I really enjoyed the level design and deep movement mechanics. Visuals and OST are very stylish and great too! I have probably completed the game 5 times already, on all difficulties, and it was an amazing experience each time! You could add more content, put this on Steam, and I would really want to buy it! 
Thank you for playing! I'm glad you enjoyed it! A full release might be possible if I find the time and motivation for it. I'm currently working on a big project (probably a steam release) and I can say from experience that working on multiple projects at once is not very efficient.
By the way, did you actually beat the insane difficulty?? Kudos to you!
