It isn't that the rocket never goes in the middle. I have spawn at 100 and rocket speed at 1000 and the rocket is clearing the middle in my game and not just circleing.
A statistic function could be that way, that you have a button, and when you click it, there is an overlay in the windows of the swords with two bars, one are the succesfull upgrades and one is the times it was broken. And when you divide the first through the last, you can get the average level the sword broke, that could be a third bar.
I think it would be cool if you don't see all the swords, or just their sillhouette, from the start. And a statistic-function would be cool, to see ho often a sword was broken whilest upgrading.
I really liked it. But I think in the higher levels it was a bit easy and it really gets busy with all that different shpaes, escpecially with some that are a little bit hard to differentiate.
It would be great to have mouse-over-tool-tips for ressources and stuff.
Also sometimes I have the feeling that going on a date per repeat button doesn't cost me anything. I guess this is a bug?
So, just completed the game.
I appreciated the physical and chemical aspects in the game. This is a nice change to the idle-game concept of creating an universe out of tangerines or cookies.
The scrolling in the game window is feeling a bit clunky. I think you should try to reduce the overall size little bit.
And then it would be cool to have some functions, like hiding completed missions and quests, or a button to buy a custom amount of upgrades.
Glad you like it:)
