It's not that simultaneous combat is bad or even unpopular; It's that your graphics don't depict simultaneous combat. Change your graphics, not your mechanics.
I like the game, it seems really novel as far as survival games go. As far as suggestions:
I would like bosses not to respawn after they are killed.
The swords you get from boss-kills cap at 25 damage for sword 5 (I think) which makes swords 5-8 equivalent except for aesthetics. I actually like that, but you should be aware of it since it increases linearly before that and so might be a bug.
The sword's placement near your body is weird at first but I got used to it and it actually is pretty cool. You should include a tutorial/instructions on that though.
Enemy hitboxes are sometimes weird. In particular, whenever an enemy gets stuck on an obstacle from the side (which happens frequently) their arms and head are not valid targets.
MORE CONTENT! (Zones and stuff).
Thanks for the suggestions and positive feedback! I see you topped the leaderboard which is awesome haha. I'll consider changing it so bosses don't respawn in the future and I'll look into the enemy hitboxes because I have noticed they act strange when stuck sometimes. I'de love to add more bosses, zones, and content in the future but first I gotta fix up a lot of the small stuff first! I'll also look into the sword thing I just woke up so I'm not really sure what I've done with it lol.
I'm currently working on Kolojang's recommendations but I might have to completely redo the way I handle movement because I've programmed it kinda funny and can't find a simple way to remove the sword switching hands without other problems arising.
So, you can sell ships and stuff you don't want. For example duplicates. The inventory limit is significantly larger than the number of spots you are allowed to use in a battle. The lives system doesn't get in the way of playing if you are careful at all, and buying more lives is not the way to go at all. This game is, first of all, primarily single player (multiplayer seems to have a lot of network issues) and, second of all, NOT pay to win at all. Everything you could buy you can get by playing, and within a reasonable amount of time. Even the pay-to-get currency can be obtained relatively easily in game. I don't know why everyone is complaining so much.
purifier doesn't count judgement kills via thorns from holy light/holy armor. Judgement also doesn't heal correctly in this case, though the text does appear properly.
The treasure vault should let you select your treasures and give you a brief bit of fluff for each, to help give a sense of accomplishment for acquiring relics.
Sorry about that! We actually created a description for each individual item you get in the game. But that was scrapped and it looks like it was a mistake. In future releases we will make sure not to repeat the same mistake.
The new tutorial is fun a fairly well done but doesn't cover infinite loops, which are (I think) fairly important to Vespitole strategy. If you ever get 11 cards in your hand, you win, which is pretty important to know.
Awesome game. To beat Lord Hammond: 1) clear the floor of all other monsters. Be careful not to aggro him while doing this, it might help to know you are always safe on the furthest top and bottom rows. 2) Aggro him from as far left as possible. You will know he is aggroed when the message 'Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn' appears over the general area he is in (the message runs off the screen). 3) Immediately run left, using the staggered blocks for cover. Hope the Cthulu Spawn he summon don't catch up. 4) Once you are to the far left of the central area (or one block to the right of that if you want) wait until Hammond shows up and give him a beat down. He'll be on his own, so if you made it this far you can probably take him. He shoots very damaging (6 I think?) fireballs so don't let him get a shot off. I recommend ending your turns diagonally adjacent to him and protected by the blocks.
