Things I noted down and other from the top of my head:
- It would be nice when on the popup inspecting your hero, you could left mouse click on other heroes to change (instead of the right mouse click - I think it's more intuitive)
- An end combat stats screen. This is a must-have for me! I'm guessing it's probably coming but for the demo, it doesn't exist yet. Either way, I'm putting it out there. Seeing how your party performs is a must-have for this game (DPS, HPS, damage taken, per character, yada-yada, you know what I'm talking about).
- The music is good for the game style but when heard over and over again it might start to get a little bit too "annoying" as in repetitive.
- For the sound effects, they're good but it's pure chaos when you have 20 different ones playing at once over one another. Probably there's no other way but I might as well say it. Extremely hard to identify what is happening on sound alone. There are games in which, either the sound effect is so unique or awesome that hearing it immediately lets you know what is happening (like an *ultimate*:)
These were the things I thought could be improved but then again, this is all just a matter of opinion so take it with a grain of salt! TLTR: I loved it. It's my type of game (love these party management auto-battlers) and I'm 100% playing this when it comes out :)
PS: I know that these characters are unique (they're awesome btw!) but maybe there can be an option to randomize the name and let the player rename them? This is my content creator half kicking in because I know for a fact, that people will LOVE to be part of the team and have their own named hero on the screen battling... or dying :P
