Loving this game

But quite a few things that can be added/patched. First things first audio tends to go out it has happened a couple times easy fix by closing and reopening. Another which isn’t a big deal but lol is the fighter move across the screen without even moving their legs it looks so funny. A couple things i didn’t like so far. One was that it takes KOINS for every thing, why wouldn’t we be able to just remove accessories without KOINS. Also i only need 20 more pulls for limited summon, me thinking it’s like most other games where your pulls will rollover. It didn’t seem to do that so it restarted back to 80. Also one last thing i like to add as well. I hope you can add a restart button for character we don’t use anymore so we can get back all our resources. It takes so long to get resource. You would make us very happy by adding this
Other than that I’m addicted

It’s ok

The gameplay isn’t what I would expect from a mortal Kombat game honestly. But it’s not terrible, one of the few things I have issues with is that there isn’t any x rays or fatalities. In the trialed it shows one but I’m not sure if that’s tied to the 5 stars in the game. Which leads me to my next point, you really don’t get much to summon for the premium banner. I know it’s a gacha game but Jesus, I got halfway through scorpions story mode and barely have half of the amount required to do one multi on it. The story also has a very quick difficulty spike which explains why there is a auto farm in the background. I’m pretty sure it’s not expected for you to blitz through the story since you won’t have enough mats, unless you buy them, to upgrade you team in order to progress easily. The menus seem to be a little slow? I’m not sure but I’ll click on a button to either go back or select something and it takes a sec for the game to register it. I think another quality of life thing would be to click and hold on affects such as bleed, etc since this game is using terms that aren’t really common. Especially on the armor sets, I understand what haste is but I would like to be 100% sure on what it means on the context of this game.

Mortal Kombat onslaught developers please fix these problems

This game has a lot of issues. I do like the designs of the characters and I like that there is cutscenes with voice actors but The over all game is very disappointing. First of all there are only voice actors in the cutscenes not the dialogue sessions. I fill like that was kind of lazy because I know you can afford voice actors because there are voice actors in the cutscenes. I say this because I fill like you should either have voice acting in all of the dialogue scenes or no voice acting at all. My second compliant is that this game is mostly auto played. I feel that if I'm playing a game I should be the one playing it not the computer. I do like that when you press the character when they are at full charge. Do really cool special moves but in my opinion that is not enough as a gamer I like a more interactive experience. I say all of this not to harass or be mean but to help you improve in the future and for this game to reach its full potential. I can tell from the graphics and the choreography that you have a pretty high production value and I can see that this game has a lot of potential. It’s just up to you if you want it to reach it’s full potential.
