This is a good game, i just think you could've spen't more time polishing(a proper background, sound, memorable locations, screenshake, etc...), than building this abrsurdly large map. Keep in mind, this is a jam, we have to rate other games too. I had collected 2500 scrap and 3 shards, just to find out i needed 5 shards to repair the portal. At that point i stopped playing, i did not have the motivation to find that one location leading me to the remaining 2.
Also, small tip, in godot, go to project settings -> rendering and enable "use nvidia rect flicker workaround", that prevents your tilemap from having these small flickering lines.
