It's a really fun game. I noticed a lot of small details.
One issue I found was with the world generation. In one run, I got the smallest map I've seen, and there was basically nothing to do except die.
Another problem is that, even though it's a short game, I don't think it's very intuitive. There were several times when Cobb chased me all over the map, and I couldn't figure out how to avoid him, especially once he had all of his upgrades.
Overall, though, it's a very fun game with a mechanic that has a lot of potential. I also really like the game feel, it feels satisfying to play and definitely makes me want to keep coming back.
