Hit the wall...

[EnemyStarship]

I've been really enjoying playing the game for the 4.5ish hours I've spent playing so far (so more than got my money worth I feel), but I feel like I've hit the wall on it... With only a few purple coins left to find, the relatively high bar/threshold for upgrading some of the weapons and perks I want to use, and the relative sameiness that's creeping in, I think I've hit a limit on what more I want to play on it? Just a thought I was having while perusing the forums and wanted to see what others may have thought?
