Thank you so much, we're so happy to know you found the graphics conveyed the mechanics well for you, and that you liked them too!
Yeah it's a recurrent critique the mechanic is not on theme, which is fair enough. The initial idea was around light and dark, and how the two are "joined together", in the sense that one is necessary of the other. We've strayed a bit from that - there's no real 'shadow' or 'darkness' mechanic, only one about 'light'. So, instead we opted for the story to be a bit more on theme, where the two lovers are trying to be joined together again, and the pursuer is trying to make the player 'join' the light again.
We also want more levels! We're taking a break from coding to spend time reviewing games, but we're looking forward creating more levels and polishing up the game once the jam is truly done. So watch this space if you're keen. ;)
Your last comment is very very kind, it means a lot to us to know that; very happy to hear someone's enjoyed our game so much! Thank you for your useful and lovely feedback!
