Thanks for the review, and the music thing look interesting, I'll have a look!
I'm sorry that you weren't able to play more because of your computer, was it due to a low framerate? Decreasing the fleet size in the settings might be a possible way of improving it if you're limited by your CPU (in that case I'd advise playing with fewer Leviathans and a slower charge rate to compensate for the difficulty of having a smaller fleet). If you're limited by your GPU there is probably no easy fix. I'd love to hear about what framerates you were experiencing and the specs of your PC.
I'd also be happy to try your game!
