Hey, you accidentally only submitted a .rar file? So I used extract.me to make it into a zip to then extract and play. After that it works!
The opening cutscene was really good! So is the level design and all of the stuff like... this looks impossible to make in one week! Great job!
Only issue I found was that after I died the retry and exit buttons didn't work >< so I have to close and restart it to play again. Other than that it looks amazing and I'm really impressed!
