Still didn't manage to pass the damn temple, but here are my impressions so far for those who don't know if they want to give it a try.
Screenshots look like a turd and give impression this game is a low quality indie trash.
But first impression couldn't be more wrong. This is actually a well developed game akin to some old classics.
Graphics are terrible, so is the audio, but the gameplay is incredible in a way. If you liked Deus Ex sneaking, combat and multiplicity of approaches, this is exactly how it works in Oaxaca. The world is structured as a multiple hubs, and it opens more and more along with the story. The story has multiple branches, you can certainly choose quite early in the game between two factions, perhaps more but I haven't got to that. Quests often have multiple solutions and the world makes you feel you are open to do what you want, not what you should, though there is obviously the main story to follow.
The world in the game is wicked and fascinating. I don't want to say much to take away your own exploration of it, but I did not thing of any aspect of the game world as it was copy-pasted or incompetently done. From factions to monsters, it was all done with dedication and fit the post-apocalyptic primitive setting with some low fantasy.
The player can develop character by appointing points to various skills which in consequence will affect the gameplay a lot. Focusing on stealth, hacking, voodoo, agility, combat and more allows for replays having a different game styles. Limited amount of equipment and the fact that weapons deteriorate and ammunition around is scarce adds to the challenge. Do, however, put some points in range weapons as unfortunately some parts of the game have unavoidable combat and with far away targets, so carrying a rifle to use at least sometimes is probably almost a requirement.
Overall, this is one of the better RPGs released in recent years. I was completely hooked on it, despite that the game can be quite challenging and required multiple attempts, sometimes a lot, to pass some parts of it. If you like challenge, wish to explore an interesting setting, and enjoy RPGs with gameplay of late 90s/early 2000s, then this is a game specifically for you! Even if it looks extraordinarily ugly and sounds like farts.
