Reminds me of good old-school Flash platformers with clunky graphics and animation. The good point is that the game doesn't lag as it progresses.
SCENES: Not much of content for release 1 -- basically, two scenes with female kobolds, and none with the princess. To be honest, I would expect some scenes with a damaged/fallen princess, either started by Enemies or by the Main Character, and scenes with the fallen MC, as it's quite common for such game genre. Probably even puzzles where you need to 'feed' the princess to an enemy to progress and then get her back to finish the level. Female or Futa Knights with all the consequences would also be welcomed. But it, of course, depends on the dev themselves.
GAMEPLAY: For its platformer part the dev did a good job, on the difficulty scale between Super Mario Bros and Meatboy, it's on the same level or even easier than SMB. I passed all levels and didn't experience any troubles with fighting, jumping, carrying the princess or controlling the character in general. The only thing I didn't like is that some kobold huts are invincible, so they constantly respawn your enemies.
USER INTERFACE: Everything is clear and done in the same style, although not polished, of course.
STORY: It's a proof of a concept, so no story is expected.
