AntiMatter Games has a new donation button available on their website, with incentives.
From them to you:
DeepWars has been in production since the Kickstarter drive was successfully completed, but after many requests we have opened up another way to join in on the game via Paypal donations from the AntiMatter-Games website or below. The reward levels are similar to those from the Kickstarter run, incorporating some of the stretch goals achieved there but not all – the original Kickers still get unique rewards. Those that have already pledged in Kickstarter can increase their pledge to get new rewards or change their current reward level.
