At first I was frustrated with my lack of progress in every level, but after tweaking the settings to where it took 2 seconds per tick and turning off the node drain while locked, this game became really enjoyable to me. I really liked the story! My one big critique is that to get every achievement you have to go through 999 loops. Maybe if you kept the default settings you would get closer to this, but with the settings tweaked for my enjoyment, I ended the game in 386 loops. Add in a few more to get the achievements I missed along the way, and the only thing left to complete the whole game was the achievement for 999 loops. I ultimately left the game up and running in the background all afternoon (about 6 hours) and the achievement finally popped. Other than that, the game was a lot of fun!
