Would love to see youtube-videos, there are some major change ups coming up between the different acts, think you have scratched act 1 a little. Act 2 ramps things up, Act 3 goes full rollercoaster. Same with the music. Very curious to hear your thoughts if you do get further in. Act 1 is almost a tutorial when compared to the rest. There is bunch of foreshadowing both in the environments and in the writing, see if you can figure out how it all fits together.
