Nice game, finished with a time of 4.25K. Took a bit to figure out how everything works so there were definitely some blunders early on, but after that it was pretty fun.
I feel like knowing exactly which items lead to the powered suit is the main bit of knowledge that would help complete the game faster. It's also really annoying having certain important skills only be present so late, but it's definitely part of the fun deciding if I should give up a skill in order to gain one I might care about more.
