[h3]Updates[/h3] [list] [*]Credit required amount of weapon upgrades are decreased. [*]New difficulty "Playground" is added. It's a easy difficulty for beginner. [/list] [h3]Bug Fixes[/h3] [list] [*]Fixed resolution trouble that some UI not properly sized. [/list] I received comments that the game is so difficult from most of the users. I think the problem caused by the balance that was tested by only the developer without other testers. But also I think that hard difficulty has a merit like challenge purpose. So I decide don't touch the existing difficulty possibly and adding new easy difficulty. This updates of demo version is also applied to main game. Thanks for your playing.
