Overall a very fun game! As others have mentioned, it's pretty short and easy, but I'm looking forward to a sequel.
Bug: I was able to buy infinitely many diamond chasis, so I accidentally spent all my money.
Suggestions: Speed up the movement and maybe make the map/inventory window semi-transparent.
For all the people complaining about the premium content - it's completely OPTIONAL! The game is perfectly playable without the upgrades, so if you don't want to pay for them, then don't. It's a great game, so stop complaining.
