Props to the artist and the sound guy, the graphics and audio are SUPER well polished. I love the electric and camera shake effects too, they really add a ton of oomph. The controls felt really good and the mechanic itself is really unique and fun to toy around with. I also really enjoyed the boss fight in the end, since it introduces a different challenge altogether.
Most of my gripes with this game concerns balancing. I found out that once you connect the loop, your character essentially turns into a hurtbox and you can run into enemies yourself to kill them. This trivializes the game, since there's so many hearts and you restore back to full hp after each level. I think it's a lot more interesting to kill enemies by trapping them inside, but what I would've liked to see is the loop close in on itself after you connect it. I found it a little annoying to kill the slower moving enemies since I had to drag the loop myself. I think it'd also be so much more satisfying to trap a bunch of enemies, then kill them all at once by making the loop shrink. The other issue I have is in the final boss fight, sometimes the camera goes wonky after I close the loop. It might be because the camera shake is super high when hitting multiple enemies.
Overall though, definitely one of my favorite games I've played. Love the concept, and I had a ton of fun playing it.
