It would be nice if the gold earned was displayed more prominently on the screen. It would also be nice if purchasable upgrades were highlighted. Good game so far.
It would be nice to not have to move back and forth between tabs to see if any upgrades are purchasable. Either a notification that upgrades are available, or have them in the same tab as the clicking one. It would also be nice to see what the prices are without having to mouse over each one. Seems like it has some potential though, keep it up.
I strongly disagree with the comments saying that the developer shouldn't have said what they're update goals were. The only problem would have been if the developer had set a goal, passed it, and failed to explain why. The developers have been very good about why updates haven't been released when expected. Nobody can prepare for every possible outcome, and the problems with the release of updates have been out of the direct control of the developers. The worst thing a developer can do regarding updates is to go completely silent because I don't want to check everyday wondering if development is dead or not. This is something this game is not guilty of, and the reason I keep coming back, so stop beating them with a stick for not releasing updates on time due to unforeseen problems. The developers are human, and those comments are very discouraging to see so little understanding after putting in so much work.
Just a note about getting free gold from the pause screen. That doesn't mean to press space to enter the upgrade menu, but to click off to the side of the screen so that the game pauses and asks where you went. you'll see lachs picture in just a few moments, not minutes.
For those wondering about the tulip puzzle connection, the order of the tulips in the vase corresponds to which cup they appear on the shelf in; left, middle, or right. If that connection wasn't hard enough to make, you also have to count the red one twice since it appears in the middle cup twice.
This is easily one of the best launch games I've played. Also, some tips for those having trouble with ace 3 achievement. Don't use the boosters at all on earth, have radar 2 equipped, equip the highest mobility fins not worrying about air resistance, and use pieces that are as heavy and high fuel as possible, and cut out engines often to keep from going too fast. The places to be most careful are right at the beginning, then in the upper atmosphere, and the beginning of space. Maneuverability is worse in space, so pulse the boosters to change directions quickly, then cut engine to lose the speed.

Thanks for the feedback. Actually if you stay in the upgrade tab you can also click on the little duplicate evil and so avoid going back and forth.
