Hey, just saw this and immediately loved the concept of a wondering soul I have to help - the art is so pretty too! Problem is, I think some text appears to be broken (I think the fonts are missing) and I needed some sort of tutorial/tips on what to do... As a result, I couldn't play for too long, so the following will be some speculative comments - hope some of them will be useful!
-I can see the start of a great story here. Different souls, their personalities, their goals, what they are running from or towards - a small intro scene could go a long way at hooking players
-Somehow, the soul seems not to be responding to my inputs... it stops and accelerates as it wishes. I think I'm supposed to be hitting the space button to speed it up and slow it down... right? (just retried it, I think I get it now - you activate the ability and have no control over how long it lasts for... good idea to challenge the player, but it did take some time to pick up on it)
-The cover art is beautiful! Made me click instantly :)
-I like that there is a score card at the end, it'd be interesting to show the consequences of failing to guide the soul
Keep it up!
