Hey! I really appreciate you getting to the end! It warms my heart to see someone get to the credit sequence! I do completely understand that this is a long game and not everyone have the time to play all 9 levels and that's totally okay! This game has a Autosave feature that whenever you feel like you want to come back, you definitely can and continue on the level you left off (though this is not communicated clearly which I do apologise).
I'm glad you notice the movement and how it is with no punishing penalties (sliding, falling off, etc). This game was never designed to be a rage game and probably will never be since that is not what we are aiming for.
I am aware of the non-natural exit of the credit scene which is unfortunate. This happened due to the time constraint of the game jam and will definitely be fixed later on!
I'm glad you noticed our selection of the music. We used 10 tracks in total and those music were made by Scott Buckley which is a very talented musician!
As per your reccomendations, I highly appreciate your thoughts and we will definitely take it into account! There are a lot of things that we wanted to implement at the start (the lines glowing one by one, the lines showing at the end on the credit scene without the primitives, and many more) though due to the time constraint, we were not able to implement everything.
After the voting period ends, we will definitely be improving the game more and more to make sure that it fits to our vision!
Thank you again for playing it till the end!
