sadly game has no open assets :( i rework all sprites by hand but planning to change this sprite approach to skeleton based animation how original game did. When i done with game port i will publish all assets i reworked from the game. If you interested for more content from original game and concept arts check out this google drive archive that i found into old youtube video description
(archive done not by me)
