Hi everyone,
I have just released a new version of the game: V.1.2, which includes some nice additions and other amends:

• Every monsters invasion needs a mother.  In hard-mode at the end of the last wave, there will be a final new monster. A big one. Keep your nerves and don't waste the last couple of bullets you might have :)
• Hard-mode now also shows an alternate ending (more rewarding I guess).
• Slightly Improved game-over stats
• Crawler animation improved
• A new random situation has been added to the scavenging phase
• Minor bug fixing
• Ready for version 2.0 of the Playdate OS (by adding also a disgusting nice list-view icon)
