Deadly precision Destroy 50 hostiles via critical hits.
Well done, please! or simply
Well done (hidden) Reach critical temperature (500 units).
Just one more minute! or
Just one more turn! or
Just one more level! Have 10 hours of cumulative play time (excludes AFK time).
I thought to put 100h in the latter achievement, but then people might want to AFK to get it out of the way... And completionists will be put off by such an achievement, even though it will be obtained by the time they obtain many other achievements. I feel like people who spent <10h don't aim for specific achievements yet, or at least are very close to 10h mark. Or maybe just make it hidden? But there might be more "one more minute!" feel for players around 10h mark than ~100h mark. It probably needs to be obtained mid-run, not on score summary. Or maybe add one for 10h and then a hidden one for 100h (
I have a life! I swear!)? Needs to state that it excludes AFK time, otherwise people will look at steam.
Man, I really like all those achievements. More than I expected. And have suprising fun coming up with more
Going for 512 now!
