For the balance, no worry, it's what i tought, it was more to say it and give my opinion ^^
Also, sorry for the misunderstanbing, when i said "cool thing to add others species" i meant to say it's cool, because there wasn't the werewolf before from what i remember, so it was a possibility that you would have just added news ennemis but not necessarily new playable species, so it's a good surprise too, furthermore you plane to add some others, so i just said it's a cool thing, i was not saying it to say you should add more x)
well in fact it would be cool too, but you already planned it up to five from what i understand so, as of now, it's fine ^^
+ i don't especially have others species in mind, could be a lot of thing, the classiques goblins/orcs, a Beholder(i believe it is the english name, in my country his name is a kind of fusion betwen Tyrant and Eyes "Tyrannoeil"), maybe zombies and vampires, and slimes, classicals too
but the slime may look very similar to the tentacle monster, i believe it depend on how you make it
Ah and Dragon could be fun too, but it probably have to be a mini/cute one lol, and a Minautor why not, it's really dungeon like, they jus tpopped to mind after i wrote xD also, a Mimic(chest) could fit too
well, in the end all theses monsters came to mind, lol
though it's still up to you to create whatever monster you want, i believe, by it games, books, or anything else, created with how you feel like creating are way more entertaining, thay have something more that cannot be explained
of course it's cool to ask and listen to ideas, but i believe what others want should'n overlap with what you wanted to do (if it mean your ideas or their ideas, but if you like the ideas or/and it fit what you wanted, there's no problem then !)
far from me the idea of telling you what to do, obviously, i just hope you'll do what you like without restricting too much because of others ideas if they are not to yours taste/envy ^^
so just, don't force yourself to add something you weren't too keen doing, it'll somehow loose some charms
(dammit, reading myself i can believe i'm giving psychological guidance T.T xD sorry about that, don't take anything personnaly, i just went and wrote it like that, it had abosulutly no others meaning, nor to make you change yours ways of doing things ! sorry 'bout that xd)
but thanks for asking, for now i'm just curious about what kinds of species you had in mind
well, maybe i spoke(wrote) a bit much for nothing, but i look forward to how you'll develop your game, escpecially since you're willing to add some more complexe mechanics, the game have potential to grow ^^
have a nice day :)
