This is some really tightly made EDM! I love all your synth choices and your instrumentation and mixing are super super clean. I think you've done a great job writing some awesome tunes and they fit together really well (especially with the longform mix, love it). What I am missing is the vision of what the game this goes with is all about - it's hard for me to tie it to the theme of going into my world since I don't know where we are!
I don't think you need to sell yourself short as a composer tho - you're showing off some great chops here!
