I was able to gather all the items, but ended up in a room with no exits as well and no win state, I even played it again to confirm I didn't make a mistake and this time I was able to be in the "larger" area while having all five artifacts, but couldn't find an exit from there either.
Would have really wished music/SFX on the actual game, since the main menu music was quite nice and felt fitting.
Game itself looked alright and the movement was good, but wished there was some story or reasoning for the artifacts or at least an ending with all of them. But good work on finishing a game getting it here on time! :)
