The best idle games not only run on their own, but also allow you to create progress via interaction. Something as simple as being able to click the fishing rod to speed up reeling would be nice.
Aside from that, the upgrade system seems rather sparse at the moment. There's a lot of potential here, though.
When you're selecting classes it should have text explanations of the differences between said classes. Having foreground objects obstructing the targets is annoying, particularly when there are friendly targets.
It's not working for me in Chrome. I have to click on it before I can press enter to progress, and on the next screen there's a silhouette and a big blue outline but not only can I not type anywhere in game at that point, I can't click any text fields on the page and type in them either. I had to reload the page to make this comment.
I like the way the planet changes as you upgrade. There needs to be more upgrades, though. There especially needs to be a way to upgrade clicking so that you get more than 1 per click. And after a couple of water upgrades it started lagging pretty bad. It doesn't seem like it ought to be that difficult to run.
Could use more upgrade-related visuals. Also, I've maxed out reaearch at 50 but only have 8/10 ships with no apparent indicator of what I need to do to unlock the other two.
I didn't want people to be able to go away forever then come back to buy everything. :/ The storage limit was one of the last things I added but I think.. it is at a good place.
Would prefer keyboard controls, especially in the later game when the knight is less likely to be centered and often manages to wind up at or on the wrong side of the mouse cursor.
Needs more enemy variation. Need the ability to call out more than one enemy at a time. Tower variety might be nice, too. And x2/x3 speed as purchasable upgrades.
The income is too low - at least starting out. Particularly for idling. The ores have too many HP with too little reward. And gems are a bit too few and far between.

I'm made a fix for this, but I'm unable to upload the new version at the moment. It just goes back to the previous version.
