I got a report of Mysterious Space failing to launch entirely, which made me realize "hey! Mysterious Space needs some way to report crashes to me..."
fortunately, I was able to find this: https://crashreporterdotnet.codeplex.com/
it's super-easy to add to your application; if you use C#, I'd recommend it! although it's been in Mysterious Space for, hm, maybe 10 minutes, so take that recommendation with a grain of salt :P
other notable changes this release:
* fixed "blessing" effects of bombing weapon and alien teleporter accessory
* re-added forcefields to the game - obstacles that appear on planets. they went missing some time in 0.4.2, and I had let them remain missing for silly reasons that were silly. so I added them back.
the full changelog is (or will soon be) on mysterousspace.com but seriously, there's not much else to see.
as to steam keys!
everything's good to go with itch.io: if you PURCHASED Mysterious Space through itch.io you can now pick up a Steam key through them! (if you got Mysterious Space "free" through an itch.io key, you won't be able to get a Steam key.)
I've also gotten in contact with groupees.com about sending THEM Steam keys; I haven't heard back from them yet, but as soon as they let me know how many keys to send, and where to send them, I'll get the keys to them!
I'll let you know when that happens with another announcement :)
thanks for playing, guys! :)
