I get a graphic artifact on the 'curved' outdoor sections,. a less than full pixel bleeds over the edges. I think you can fix this by adding some padding around your sprites/tiles, just leave an extra pixel or two of empty space around them and this should go away. The game reminded me of Seiklus, I thought it was made by Chris till I checked the credits. Good luck with it, Perennial is a very nice game.

Mr. Asf-Dag - just start the game again and continue, it auto saves.
