I think a long time ago, I heard about the Doom Roguelike and never bothered to check it out, but after getting into Rogue and Angband recently, I heard about it again and this time decided to give it a download. Long story short, it's awesome and I'm hooked.
Having played a fair amount, there are some things that have been bothing me. So I'll bring them all up here. I know some have been discussed, but I want to be thorough, so I'm going to list everything that comes to mind. Some are features I'd like to see added, some are things I would have expected and I'm wondering what the deal is, and others are just comments on features already in the game. Sorry for the post the size of a novel.
-Sound effects. This isn't a huge issue, but as someone who's been playing Doom since it came out, I hear sounds and automatically assume one thing, when in DoomRL, it's probably wrong. Imp death sounds for shooting a former human, demon death sounds for killing former sergeants, spider mastermind death sounds for arachnotrons being shot, etc. It's just frustrating. If these changes are because you feel they fit better, I'd request perhaps an option to switch between original sound effects (emulating Doom's behavior), and your modified ones(current DoomRL sounds).
-Enemy projectiles destroy walls? Barrels and rockets I can live with, but little fireballs seem silly destroying chunks of the walls big enough for a human to step through.
-Some symbols don't make any sense. Why c for demon? d or D would have made more sense to me. B for hell knights had me confused for a minute as well. I get why you did it, but I'm not sure H wouldn't have been better. And all the globes, I would have made color coded o's, but that's just me.
-On the topic of symbols, after clearing out a level, it takes me a second to find the stairs again on the map because it blends in with everything else. I don't know if there's something that would stand out more.
-I think you're already planning on fixing this, but the exit after dying is annoying.
-Simple typos. "Really" is often spelled "realy", for example.
-Is it just me or are chainguns better than plasma rifles?
-With Lev1-9 of Phobos, you use the midis from E1M1-M9, which was cool, but after that, you start skipping midis. E2M1 and E2M3 are gone, for example. Is there any reason why they are missing? I'd like to see all the midis from Doom. (Ignore this if they are used later, as I haven't gotten that far.)
-The blood and corpse effects -- awesome. It's really satisfying to see a room almost entirely red after slaughtering all the hellspawn in it.
-I found the nods to the Doom Comic to be quite amusing.
-Are there any plans for new enemies? I know revenants and mancs will probably be in at some point, but it would be interesting to see a few new monsters like the former commando. Personally, I would suggest some variation on the imps and demons. Tougher or faster versions, maybe.
If you read through all of this, thanks. And fantastic work on the game.
EDIT: Added some stuff.
