The code to the safe near the sunken boat is 3-2-8. You're straight-up given the code when you need what's in the safe, and you can't use what's inside before then. Still, it'll save you a minute-long round-trip to get the safe contents.
Did you pay to get on the front page? There seems to be no other explanation, considering the low number of plays and the mediocre rating. Besides which, the game's controls frequently lock up for discernible reason.
You know, as riveting as this story about robots who who removed their emotions is, I can't help but notice that you never make a compelling argument for WHY beings of entirely rational thought must be in a permanent state of suffering, or why emotions are inherently good. Yes, humans are nothing without their emotions, but byte-people aren't humans. It's rather arrogant to assume that what works for us must work for non-organic lifeforms.
Right now, there isn't much incentive to invest heavily in the more specialized upgrades, as long as upgrades suitable for all purposes are available. But one way you could make elemental attack and defense more tantalizing is if, instead of one endless level, you offered a campaign of a series of levels each having a unique assortment of enemies. Some levels would require you to invest in anti-red upgrades, some levels anti-tall upgrades, etc.
I think I see why the "Go me" button after completing the basic levels doesn't work properly. After completing the challenge levels, it tells you you've completed the basic levels and offers you a challenge. So it seems that the basic level completion screen and the challenge level completion screen were accidentally swapped.
The main problem I have with this game's direction is that it seems you couldn't decide whether you wanted a spooky and enigmatic atmosphere like Submachine, or a wacky romp to faraway lands like The Life and Times of Scrooge McDuck. So you decided to go for a little of both, and it just... it doesn't work at all.
You know something? I don't feel bad for the Dibbles that gave their lives for this petty quest. It's not my fault that they're too stupid to realize that there's other ways to form steps and blockades without pointlessly dying.
