OK, finally managed to put down the game. Overall, it's very nicely done. The death lines are hilarious, and I found myself literally cackling maniacally as hordes of bots went up in flames ("WHY WAS I PROGRAMMED TO FEEL PAIN!?"). But what finally enabled me to tear myself away from the game was the daunting prospect of having to organise my inventory and select the parts to use. The inventory management interface is very basic, and doesn't really help much.
Right now, the most important thing that I think needs to be done is for the inventory management system to be overhauled. The majority of the space reserved for any particular item is taken up by its image, which is pretty much the least useful piece of information that can be given about any module. I propose that the module selection interface, instead of using a thumbnail layout, uses a list layout, with each row containing the information that is currently in the tooltips, and tooltips for the rows giving a comparison of the exo stats before and after equipping this module. Also, a way to sort modules so that we can easily find those that give bonuses in this or that category would be very useful. This way, it'll be a lot easier to manage the inventory, because that part of the game is, I think, the only part that would be seriously annoying enough to drive people away.
