Ahh ok, so I think I ran into some kind of bug when I played the first time and left the map. The second and third crystal didn’t give me a range increase (except for the bridge) on my first playthrough, maybe because of the way I left the map:
When I left the map (I circled the exit in the attached image), I thought it was intentional, and the game was gonna break the 4th wall. I noticed that when I left the map, I could “pick up” the UI, including my own crystal from the Power UI. I thought “wow that’s so cool”, so I picked up my crystal “from the UI”, but perhaps that broke something because I never noticed my range on any of my tools going up (except for the ladder?) when I got new crystals. (To get back to the map, I had to repeatedly ‘pick up’ my crystal from the “Power” section of the UI all the way to the right side of the map, not sure if that makes sense but try exiting the map via the image I showed, and then go all the way to the left and pick up your own power UI).
When I played the second time, each crystal gave me massively increased range and I was able to pilot the EV through the final stretch. Finished it, that was great! I really liked all of the logs and the way the whole game was contained on one screen. The music was great for ambience too. I really liked how each crystal gave me increased range (at least on my second playthrough haha), it felt super good to pick up the second and third crystal and be able to scan so much of the map at once. The puzzles were all really satisfying to solve. Thanks for telling me about the full version, I’m glad I played this.
(My first playthrough took me a solid 45 minutes to get to the point where I got stuck.)
