Watashi did this a while back, this is the first set of wonderful games watashi played made by the wonderful indie developers of this generation! This first set was Pokémon themed, and my rating for each (in play order) was 7/10, 8/10, and 4/10.

Pokéadventure was a fun short little Platformer/Run-and-Gun game, that watashi enjoyed for the short time watashi played it. The few gripes watashi has is that it doesn't really tell you the controls (though it's probably watashi's fault for not trying the arrow keys...) and that there's not really an ending screen of any sort. Other than that it's a pretty great little game that Watashi'd love to see continued.

Pokétale was the longest of the three. It's your standard Pokémon game, so no real problems gameplay wise. My main issues are that watashi's eardrums were getting blown out because there's no effort to keep the custom tracks from being the same volume as the tracks that come with Pokémon Essentials. The overworld design was mediocre, it wasn't super bad, but it also doesn't have anything very memorable about it. However, after defeating the first gym leader there's a Cerulean Cave esque section you have to go through in order to exit the cave. The text is hard to follow sometimes, as it's in broken english, but watashi doesn't think that's enough to dock the score at this stage in development. Overall it's a great little demo that watashi'd also love to see continued and revised.

Pokémon Golden is (from what watashi could tell) just the default Pokémon essentials map with a little bit of change in the first area and the intro. Watashi honestly can't tell whether it was a joke or not. The changes show promise, and if the creator-kun wants to continue to work on it, you could have a fairly decent game. However at this point, it's really not all that interesting.
