I need feedback

I have been gone for a while to generate ideas I just need to know if its well balenced it should take 1-3 hours to beat maybe a little more but I'm unsure what bugs are hiding in there and it would take ages for me to see. can you try my game and please give me your honest opinion if you have any questions feel free to ask me (also if you have tried the game before just know that progression reset due to a bug don't worry I fixed it but your progression may have been affected also once you reach milestone 8 that's practically endgame)

I tried your project and it's really cool! I would just recommend making the interface more user-friendly and smoother.

in what way may I ask?
