I should probably have seen the Early Access reviews before purchasing it, but this is where you get a bit more savvy about positive reviews than negative ones.
And frankly, this game isn't too bad. It's just not... fun and doesn't feel too interesting. Think Doom and Binding Of Isaac, but with a worse Health system, weapons that feel powerless at times, and surprisingly bad frame drops at times.
Paranautical Activity (Deluxe Atonement, for its re-release after the minor controversy), is a rogue-lite FPS game, that seems to take notes from Doom and Binding Of Isaac. Yet, it seems to do it in ways that work against the game. While it does use some of the things (fast paced shooting, randomized rooms and floors, varying stats on each character), it doesn't use it well.
Weapons feel quite good to use, although some of them feel rather weak. The shotgun, from my point of view, felt like the biggest let-down of all the weapons, with the bow being powerful and one or two-hitting enemies, with no problem.
Power-ups feel nice too but with next to no proper explination as to what they do, when you pick them up, leave you to guess what they do, for whatever situation you're about to plummet into, with said power-up.
Enemies are... alright. Mostly tedious to deal with, since some range from simple "fire a bolt, wait for a while, rinse and repeat" to "'bullet hell'-like spam". Surprisingly, the most annoying enemy I faced was the floor sharks. Why? Tank-y characters can't dodge well, and with the floor sharks, I've ended up being juggled by them, shooting them with a shotgun that did abysmal damage, until I either died or completed the room that way.
Levels are pretty much the same square box, with randomised preset props, and enemies are dumped in when you enter. Nothing to write home about, except for what could amount to some problem with moving under staircases. Ended up getting stuck there, which has broken the flow of gameplay, quite a lot. There also seems to be some odd dissonance with the enemies that spawn in some rooms? Sometimes you get enemies who spawn in there, who get stuck in parts of the level geometry and just kinda... sits there.
The characters have different spawn weapons, health and speed, meaning that you have some variety in what you can do and can't do. And by variety, it boils down to how far you can get with the fast characters. I mentioned above that the tank-y characters are slow, and even the extra health they have, just makes them a sitting duck until they die. Along with some of them getting weapons which would be ideal for fast characters, since they promote "attack-retreat" tactics, they work against the character, requiring them risk taking hits, which they most likely will, to pump in shots that don't feel like they do much. Compared to the bow or the sicle, the shotgun feels like the ♥♥♥♥♥♥ pistol you throw out the window, as soon as you see anything remotely non-pistol like.
The bosses are... okay. They look interesting, but their design and looks are pretty much meaningless, since most of them just fire shots are you, non-stop until they spawn enemies or do some third thing that makes them slightly different from each other. And, honestly, they could be interesting if most of them didn't feel like the same boss. They just move around the area and shot, not really doing anything else, than the animation their set. Which sucks, cause the bosses I fought, looked really interesting.
The game itself, is it worth it, even after all that I complained about? For some people, if you've run out of rogue-lite games, akin to Ziggurat, it could be. If there's some more tweaks to the game, such as a revamped health system, characters and weapons being buffed, as well as some changes to make bosses less dependent on luck or power-ups, it can be a very fun game. Also the font is pretty damn ugly to look at, in the menu. And the menu looks really amateurish, which is kinda sad, considering a lot of indie games do a lot to make the menus look presentable.
Was I satisfied with the product? No. I felt like I bought a game that could've benefitted from more time in Early Access, especially now that we have a new dev team who works on the game. Hopefully, some future patches can make them game more fun to play and less annoying to deal with.
Do I recommend it? As you saw above, I don't. If you want to jump into the genre of rogue-like or rogue-lite or whatever the cool kids call it, look for a game like The Binding Of Isaac, Ziggurat, or look up some games within that genre on your own. If you really want it, prepare for a game that you may dislike or find too tedious to keep playing.
