Itch Launcher fails to run the .x86_64 because its trying to install it instead of executing it. Consider zipping it or something. Works fine when downloaded from Net tho.
Consider not packing everything into the Executeable, allows more modularity and easier bugfixing on your Assets/Overhauling them if necessary, alongside reducing loadtime on Startup and reducing RAM usage by not forcing everything to be immediately loaded and kept in RAM.
I'm assuming your HUD on the mainScreen/MissionSelect is temporary.
Loadout Menu could be an actual Camp or Ship or something, instead of a currently very placeholder-y feeling Screen. Mission Select feels a bit seperated, instead of built into a Story or something.
I like the small Lore tidbits on Items tho.
Fristivars Portrait cuts of on the Left. Should be either on the Screenedge, or be finished.
Text on the ingame Log is unreadably small, shouldn't scale with Windowsize I think. At least not that much. No Idea what the Shortcuts are, if you're not explaining them in a Tutorial, at least make the Titlescreen Info available ingame for now.
After dying, I couldn't select the Hunting Wolf back into my Party for the next Try. Fixed it after clicking the little Arrow in the Hero, no Idea what it does tho.
The first Mission already is also really hard. But you do a pretty nice Job of building up the Usage of Items and the correct Pathing, leading into carefully exploring the Darkness I think. With some Information and hinting that you should be careful, and that Items are here and there etc. this could be a nice Tutorial Mission I think
Whee. Sadly lost my Wolf tho.
Apparently I could take multiple generic Units, I didn't know that. I also don't know if I like it that much. But now going with maxed out Unitcap, should be a lot easier I guess.
Second Mission played a lot differently then first. While the first was more of a Partbyased Game, the second felt more like a small RTS. Gave me a bit of a Pixelart Age of Empires feeling. Not that I disliked that, but I don't think the Amount of Loot management would fit into that many Units.
Its tough to play on Trackpad, but its still pretty enjoyable. Which there was a Way to either keep the Loot window in a Character fixed on a Screenposition, or have it there permanently, annoying to manage Stuff while moving otherwise. Or in general.
Took ~1.5h for the first 1.5 Missions I guess. But I was doing other Stuff on the Side a bit aswell, so maybe half an Hour per Mission at the Moment?
