Size of the character

Size of the character

First I would like to thank you all because I really like this game when the first time I discovered it!

Now I have a question. When I played flare (version 0.19-1 on debian) today, I find that the character, etc. is very small when the resolution is set to 1600x900. The screen looks like http://imgur.com/NtSm9Ie. I can't even find the character I play because the color is bit similar between background and the game character. So my question is - any way I can scale the related stuff e.g. character, dialogue, etc. to a bigger size? If yes, how to achieve that? 

 

Thanks
