The clouds are gorgeous! I really liked the background! Also, never have I ever thought about herding souls, very nice!
Some things I think that could be improved:
- The sound effects were effective, I liked the dog barking, and the sound when you complete a level is funny. The music however, seemed barely audible. By cranking up the volume I could listen to it. Perhaps the experience is a bit different with headphones? I haven't got mine right now.
- The tutorial seemed a bit overwhelming, but perhaps that is just because there's a lot of mechanics right from the get-go. Perhaps making it a paginated could help?
- At first I thought I had to gather the souls, I felt confused as to how could I do it if they escaped from me. I think this could be explained in the tutorial.
- The souls can go to the top of the screen and just become impossible to bring down. I had one go to the top of the screen and another to the bottom at the first stage. The bottom one could be gathered, but it was more visible than the upper one. Perhaps making the bounds a bit more forgiving? Or making the screen move a little?
- There's a bug with the continuity of the stages. I gave up on trying to retrieve the soul at the top on the first stage, clicked on the menu and started Play, thinking it would reset the stage. What happened was that the time and soul counter just kept going on while the souls and the character got repositioned. So with a single soul I got stage complete, with 6 minutes as the timer wasn't reset.
- Sometimes I'd lose track of the dogs behind some of the clouds at the borders. If I could click on their cards or maybe adding hotkeys for the cards? Like clicking 1 to select the reaper, or 2 to select a dog and so on. That would make it easier than trying to guess where I left it!
I really liked the way you went and the dogs were very cute. Congratulations!
