Thanks for the feedback. Sorry you couldn't launch the game, resolution and sound options are on the to-do list for this week so stay tuned for an update! I will definitely investigate the issue with launching from itch client too.
Music is by the awesome Kaedalus at kaedalus.com!
EDIT: Quick update has been pushed, problem with the shader was preventing proper res scaling. The game should now scale to any 16:9 resolution although I can't make any guarantees for other aspect ratios. If anyone can provide feedback on this issue it would be appreciated, thanks :) and an .exe file has also been added which launches through itch client :)
