I haven't played a great deal of Rogue Shooter, but I have to admit I'm not sure I will.
This is my first Steam review ever, and I write it because Rogue Shooter looked like an intriguing and fun game, and I really, really wanted to like it.
The idea is a good one: a fast-paced never-the-same-twice, permadeath FPS harking back to the good ol'days of Wolfenstein and Corridor Seven.
I like the humour. It's genuinely funny and well-written. I like the weapons and mechanics, and I really like the data feature which helps you get better over multiple playthroughs.
However, there were a couple of things that tell me it's just not ready for market yet. There were four, and I'll list them below.
1) Lack of save. I understand permadeath, but there are A HUNDRED floors in this game. Why not implement FTL-like saving+quitting in case I don't have time to play until death or THE HUNDREDTH floor? Unlike Binding of Isaac, the game is simply too long not to be able to save and come back to it later, and it's not like the difficulty ramps up very steeply so it can get to a point where you're just praying for death.
2) Impossible maps. On my very first playthrough, maybe my third or fourth floor, I realised I was trapped in a square unconnected to the rest of the floor and isolated from the elevator up. This was annoying enough on the single-digit floors but can you imagine your white-hot rage if you were on the 60th floor when this happened? Or the 99th? Surely it would just make sense to ensure there was a route from entrance to elevator on each floor when it generated?
3) Terrible slowdown. The game inexplicably slowed to a crawl on several floors and I couldn't figure out why. The graphics? The number of enemies moving around? The level generation itself? There is no reason a game this light should chug like that on my computer (it's not the best machine but it runs other, heavier games just fine).
4) Music stops. This is purely aesthetic but really does affect the enjoyment of the game. I found several times that the music stopped after a while, maybe after the track finished once, and it didn't repeat. I was just running around in silence except for the meagre sound effects and it just wasn't very fun. If none of the other things I've listed were there, I probably would let this one slide. But in a game where I already have my doubts this kind of just drives home the point that the game's just not done yet.
So I'd say if you're curious and maybe want to spend a few hours messing around with a new, unique game, pick this up.
But I just can't give it a recommendation.
