+Gamepad support added
Nice game =D, it reminds me a lot of cave story (have you ever played?)
Will you make a longer game ;)?
I was thinking the exact same thing as Herbherth.
A lot like Cave Story, and that’s not a bad thing! 
Thanks, and yes I’ve played Cave Story. I’m thinking of coming back to this one day and making it longer.
Bugfix for Tess ver 1.0.0.9
There was a major memory leak in how the game was trying to detect if the player had a gamepad connected in the last release that would most likely bring the player’s computer to a grinding halt if they weren’t using a gamepad.
The download’s been updated to fix this. Please re-download the game if you’ve downloaded ver 1.0.0.9 prior to reading this notice.
(Also the korean readme was updated)
