I'm not completely sure, but the simplest option would probably be to put your music in the downloads section, and you art on the cover (or in the screenshots if you have more than one image).
i like this general concept, and i think that this has the potential of a really cool game. the sound design hits the spot, and the visuals are unique and intriguing.
several aspects stand out to me that could greatly improve the games overall quality with some tweaking.
the first is the visual contrast. though the character and goal are very clear, the platforms can be hard to make out against the dark background. brightening it slightly would make the game much easier to follow.
the next is that the character pretty frequently glitches through platforms. this isn't the worst thing in the world, but it happens frequently enough that it is probably worth looking at.
the last thing is the gameplay loop. the randomly generaterated platforms and the timer work well together. however, there isn't much at stake as the player to motivate me to reach the end in time. i think also that the feature where new platforms apear and you get more time on your next run each time you fail work really well together, but in order to motivate the player to use each of those platforms strategically, or better yet, to plan where they will be when the timer ends, some form of progress tracking, long-term improvement or simple leader-boarding will add to the playability greatly.
if you want to go the extra mile, more linear increase in difficulty as the player beats each room would polish it off nicely.
i hope you keep updating this project, since a large amount of it is there! visual details like the white eyelids and the mist-like background really strengthen the professionally of it. have a nice day!! :)
