Nice version I was playing this like 2 years ago, I like the new heroes.
Alucard is I think for now the strongest hero, with huge gold earning and his fire spell doing more dmg than it should and good auras.
Finished the game solo with him quite easily.
This game is probably not made to be played solo and save game. But if you save game with master chief, you lose your weapons when you load back.
Took me a while to go far in the game, first problem I had was with the wolf boss, would'nt jump back to fight.
Noticed once he was actualy behind the montain (near the "halo" portal, went all the way there to killl him, he jumped back to heal again then got stuck for good.
Then playing with samus, after beating sephiroth I got stuck at the halo quest after killing everything on the forest area, couldn't port in the "ship?".
I saved the game a loaded again with 30min left, tried to run around to unbug it but nothing to do, after 30min you just lose the game.
After that, I managed to finish halo quest then finish the game with some other hero.
Another bug with serge, I think it also happened with other heroes, sometimes using spell combo I end up stunning bosses forever.
Some spells are doing no dmg, some others, way more than they should. And some heroes are just too weak to solo the game their spell are too weak, you need at least one "bugged" spell per hero to finish the game without fighting bosses for 1 hour lol.
I'll try remembering a few spell that were bugged:
Terra's cure is one of the most bugged, heal at least 20times over the amount.
Samus running skill is also doing huge dmg, sonic jumping skill deal much more dmg that its writen, chrono trigger jumping spell deal 2 times more dmg than it should, but his ulti (the one with 110 sec cooldown, deal less dmg than
it should).
Alucard fire spell, when throwing 2 rocks, deal huge dmg, but his ulti, which is supose to double any auras, wont double the armor increase and reduction aura.
Many items with special spells are not working properly.
In the items you can buy, the diamond armor for 100gold give 20 armor, when other armor more expensive give less.
If you buy the special pipe item for mana reg, you'll get epic mana reg and will never need any other mana item.
The "well monster" quest is not working properly, and I just cant find the ring in the city quest, yet I went everywhere and also combined the 2 ghost items.
Sub zero polar bear transform say last 30 sec and 60 sec cooldown, but cooldown is longer also give more hp than it should from first lvl.
Many heroes need more lvls on their spells for later bosses, all spells should go to lvl 20 , so 5 spells, 20 lvls, for 100 total

.
And/or, some heroes need more attribute related spell to keep up late game. Also, you should be able to buy boot of speed at the shop, the only 2 items I found to increase speed are bad, one last 10 sec, the other increase by like 5%... lol.
Makes it too hard to kill sephirtoh with weaker heroes, too slow to come back to boss.
Anyway that's all I remember for now, sry for my bad writing its late
Keep up the good work!
Edit: few more bugs I thought about, with cloud after you killed sephiroth and get a new skill, the skill is not working correctly you dont get hp bonus and stuff like that.
Since its a "new cloud", instead of just a new skill, you lose all attributes you had bought from the shop which is pretty annoying.
Also in could's limit break, second last one deal 0 dmg, and many skill deal more or less dmg than they should.
Pikachu should be able to transform at let say lvl 100 into "raichu"? or something like that xD.
While playing goku, I managed once to stay in super saiyan form after running out of wood, stoped once I lvled up and tried to go to another super saiyan.
Most transform skill dont give the right amount of hp bonus.
Serge should be able to heal himself.
When you enter hyrule, and go left to kill the ogre, it say "here's 15pts" I assume those are attribute points? if yes never got them.
Also in the halo quest, the satyr unit, sometimes are immune to spell sometimes not is that on purpose? sometimes they are immune forever, which make them almost impossible to kill with normal attack with some hero.
If you fight the satyr close to the ally marines, they will get imba reg and will also be impossible to kill even with spells.
When you fight the zero boss in the mech quest, sometimes the laser just wont trigger, and if it dont, then when you come back before it explode, sometimes the other laser which open a path to run wont work either.
Again in the mech quest, you can enter the body armor and drop the ank, then get out of the tank for 2 free anks.
When you use -unstuck, it also unstuck the body armor.
