Man, RNG really got me on this one. Neat concept, but I just felt like I couldn't win some of them, and when I got surrounded, there was nothing I could do. But really interesting concept!
If you continue tinkering with it, it might help if the sprites were closer to circles/squares instead of being so tall. If I was surrounded on the sides (which is more likely to happen since I play on a wide monitor instead of a tall one), it means I have less room to see to run past enemies compared to running up and down. But if the sprites were a more uniform size, I feel like I'd have more mobility options during gameplay to keep going!
