Went back and finished Coromon. I think if you're a Pokemon fan there's a lot to like. It's pretty much a more challenging Pokemon game with good spritework. Some of the mechanical changes it experiments with are great (revised EV/IV/shiny system), while others fall flat (modified type chart). The mid-to-end game lull that usually happens in Pokemon games is present here too. The most entertaining part of the game is the first few hours when you're capturing the Coromon you want to use in your party. I did appreciate the larger level gap between evolution stages. So you don't already have your complete party of fully evolved Coromon a third of the way through the game.

The quest tracking system was a bit frustrating to navigate-- especially a certain part of the story that requires you to do tasks for multiple people. The logbook wasn't descriptive enough to remind me what needed to be done after a long break from the game.

If you have the Pokemon itch this will 100% scratch that itch, but I don't think it has the level of polish required to be a full-on imitation.
