I am glad that you liked the game and I hope it didn't take you too long with the difficult parts you mentioned. I will let our composer know that you liked the music. It sounds like you made it pretty far into the game and I am glad you were motivated enough to stick with it despite the difficulty and any bugs.
I think we unintentionally made it way toooo challenging :). Our intention was to make something that required a level of skill and mastery, but keeping in mind that its a game jam and people may only play your game for a bit. So I think we need to retune the difficulty a bit, after the jam is over. I apologize for the bugs you mentioned. We are working on delivering bugfixes also after the jam is over. The last bug you mentioned is a surprise to me, but we will look into it. Let us know if there is anything else you would like to see patched.
