I'm a bit sad because this game is so well done that with a little bit more polish (and probably more time) it could have been excellent.
First it is gorgeous to look at. The designs may be simple but they are following a given aesthetic which really nails it in my opinion.
Then let's give credit to the voice actors which are, i assume, amateurs. It's not an easy thing to do and the simple fact of trying deserves praises. It's not perfect but it adds to the universe immersion.
Now the gameplay. I'm a huge fan of Tactical-RPG games so how could i not love this game system ? It's simple and works well. The AP management is a real good idea which open a lot of possibility for both offense and defense. However it takes a moment to clearly get this due to the lack of tutorial. Especially for how (i assume) types works,there are no clear indication that Envy Attacks deal more damage on Greed enemies (i think ?).
Despite the lack of clarity and i greatly enjoyed my experience with the game.
Btw, did you really made everything yourself ? Even the music ? Because i really liked it and wished i could listen to it more.
On a side note, i suspect you left a demo level in the level pool since when you pick a Tharsis level you may encounter a zone with no enemy.
This game feels like a rough diamond. A lot of good ideas, well defined aesthetic and style but that overall lack just a tiny bit of polish to become excellent.
Congratulations on this one.
