The game is really cool ! As you mentionned it, it's unfinished. But there is a LOT of content. There is a lot of music and even voice actors ! There is a lot of variety in the environment too. Sadly in this jam version the main voice actor volume is very low and I can barely hear it compare to the music. But the project is good, you should continue it as you said !
Good choice to give access to the developers' room, it would have been a shame not to see all the work done (even if unattainable in game) !
