dude, great video. I was laughing a lot on the goliath part. I loved your video, serious. I am very happy that you guys seems to like it. 


Hm, feels to me like that what I'm earning out of the fights dying in wave 2 again and again is not what gives me much progress. I think the rewards should be bigger, especially when the game starts. Why would I want to die in the same wave again and again? :)

Apart from that, the graphics, sounds and atmosphere are great.

Good job!


Thanks for the feedback <3

I'll try to make the rewards in the horde better in next update.

So, I'm in kind of a weird spot on this one. The tutorial is amazing, the mechanics, movement, pacing, lighting, and combat all work wonders in that dungeon crawl format, but it felt like they kinda fell apart in the point defense mode. I'm not sure which will be the focus of the main game, but I felt the scifi dungeon crawling was by far the strongest use of the current mechanics.


Dude, great video. I am very happy to see people playing the game. I laughed a lot in the part that you were facing the boss of the tutorial kkkkkkk.

I will try to launch this week a new version of the demo with two missions with gameplay similar to the tutorial.

The stamina management was perfect against the tutorial boss, and a bit of trial by fire to learn the mechanics too. Definitely one of the stand out moments in the demo :)

Hey there, during file extraction I get this error, then on launch I see the start screen with no menu buttons. I can still hear and click them, but can't see what I'm clicking.
