    Pokémon Battle Labyrinth

    Story

    Hello there!
    You've been invited to participate in an experiment run by Dr. Colress of the Unova region. He has created a specialized simulation for only the strongest of trainers, called the Pokemon Battle Labyrinth! Fight your way through a gauntlet of challenge rooms, manage your resources, and build a team of Pokemon generations 1-8 in this unique, arcade-esque ROM hack.

    This game is a complete deviation from the default 8 Gyms, Elite Four, evil team game progression. Instead, it implements a classic RPG dungeon crawler in Pokémon form. Players must clear different dungeons called "Zones", and can only access shops/healing spots between Zones. Offering an emphasis on challenging gameplay and resource management over story, Pokemon Battle Labyrinth contains tricky puzzles, difficult bosses, and great rewards.

    It's unique enough to warrant a try, I'll try it.
     
    Just beaten the current beta and can say its really awesome and easily recommendable hack that can be enjoyed for both casual and hardcore pokefans alike. Reminds me of "firered vr mission" but this has more replay value. I am excited to see more release!

    I would love to share few ideas I have come up with while playing:

    Thanks! I really like some of these ideas and might use them. I will say that HM moves should be deletable, as I just tested by catching a wild Pikipek with Rock Smash and replacing with TM Protect. Let me know if this problem persists and I'll look into it.
     
    Hey, how many zones will be? I played the previous version and is unique ..nice idea!
     
    I seriously need to update my computer -.- Now google drive and MEGA don't work on it. This looks very cool, hope it does well.
     
    Apologies, I forgot about this Pokécommunity thread! This hack is not completed, but it can be played up to Zone 20 at the moment. There will eventually be 50 Zones. Feel free to follow up with any more questions if you have them!
     
    Hey, i am stucked in zone 17. I don't know what to do. Have I to pay respects in order of death or ?
     
    Hello! Before I try this, I'm curious. Have you buffed any of the weaker pokémon, or changed any typings? I'm assuming not, but I want to make sure. I really want to use a Bug/Ghost Parasect in this.

    Yes, many Pokemon have been buffed. Note however there are also some Pokemon specifically excluded due to balance/overcrowding reasons, including Parasect.

    You can find puzzle solutions in the documentation folder!
     
    A new version has been released: 1.3.0 offers up to Zone 25 and many, many balance changes! Unfortunately old save files are NOT compatible.
     
    Hey, I plan on trying this out. This kind of concept is something I think has tons of potential, especially the randomizer mode. I'd love to be able to create extremely variable settings to exactly my own liking, though I know integrating those kinds of options and menus into a ROM isn't exactly simple, so I won't hold my breath.

    If I had to pick one set of options I'd really like, it'd be a few more purist options for the pokemon. Restoring move accuracy/power/PP values, original typings, evolution methods where possible, etc. I understand the intent of most of the changes, I just don't like them. Especially with typings, you could do a more granular list to select typings you like, if you're more mixed, and you could even do multiple alternate typings for pokemon it fits (ie Ariados)

    also, independently of actually playing the game, I'm gonna guess you'll want to up the PP on some of the setup moves. I know thats a big nuzlocker thing to remove setup, but like Rest? 1 PP? What if you want to fight multiple foes between healing? Considering TMs not restoring PP is a listed feature, and I doubt you're going to have bottomless ethers/leppas, that's gonna be extremely frustrating

    Hey there! I really appreciate the feedback; it's really helpful for me as a developer to hear other ideas and different takes on features in the game!

    Even more variable settings could be an option. Because this is a decomp hack, adding menus and the like is actually incredibly simple. It's the functionality of these variable game modes that could be hard. Off the top of my head, I'm not entirely sure how to make it so on one game file you can make Pokemon have different types depending on your game mode. I imagine this could be done using two different patches (i.e. think of Drayano's Clean vs Complete versions for his hacks), but to me Pokemon Battle Labyrinth is kind of meant to be played with all the Pokemon changes in mind. (Also note that Ariados is not in the game!)

    On the subject of PP for setup moves, I would actually keep the default PP for most moves on Default mode (the easier difficulty mode), but codewise have not figured out how to do that yet. Setup moves PP are nerfed because they are inherently quite broken, but the reason moves like Rest and Recover have their PP nerfed is to force the player to actually buy healing items. If each of your Pokemon knew Rest, instead of healing your Pokemon between fights, it would be very easy to just run into the grass, use Rest, run away, then use an Awakening, saving massive amounts of healing money. On Default mode anywho, you can easily farm Leppa Berries at the Berry fields. Again, I would make the PP different in the two difficulty modes, but I am not entirely sure how to do that yet. I will definitely look into it though, thanks!

    Again I really appreciate the feedback; if I make some significant progress on how to make the default typings/abilities/whatever available on one game mode and the edited stuff on another game mode, I'll let you know! (Same thing with the PP thing)
