Solid little game, I like the energy mechanic and powerups. Visuals are pretty nice though there were many long straight passages that made it hard to tell I was moving. Some additional details or background parallax might help with that. Also because the map covered very large areas and did not show any details it was a bit hard to orient myself. I would end up back in a room I had been to before (according the the map) but not really feel like "oh I am back here". I like the sniping mechanic, it feels good to try and get that off while being stuck in place. I do wish it was the same button to exit sniping mode, I kept trying to hit that. Energy was a bit frustrating with the wall jumps, they should either use less energy or energy should regenerate more quickly after hitting the ground. Waiting for it to regen if you miss a sequence of wall jumps feels bad, and I hit that imediatly on getting wall jump. Feels a bit less bad once you have some energy upgrades.
Mentioned by others but hover sound appears to be bugged, quite annoying.
I am not sure if I reached an unfinished end or a bug but when going to another screen I abruptly was put back on the menu screen. I feel like I had a lot more of the map to explore.
