Character controller has modular jump height, which is good, but the jump animation is very odd. It feels to me like the character is trying to fly or something. And I don't think the collider changes size when jumping, so you keep hitting things with your belly.
I got stuck after defeating the king goomba. Nothing worked for me after that. I found a small hole near the sword I could conceivably crawl through, but I couldn't find a key that would do it. So I stopped playing at this point.
The highlight of the game is the art and how it's put to use in the areas. There are tons of art and collision bugs of course, with a game made in such a short time.
I was pleasantly surprised by seeing camera collision at work, being even able to distinguish between different objects.
There's no music, so that's a minus. The sound effects are somewhat varied for the coins, but not for the shooting sword. Those seem to be the same sample.
Other than the toads lying I don't know that I noticed much of the theme.
Overall a strange entry. Lots to look at, very little to do in it.
