Fun little game. Action adventure platformer. The graphics are crude but cute. A little more instruction might be better, or maybe that was just the fun of discovering it.
*** WARNING SPOILERS ***
It wants me to press action button on the sign, and the screen fuzzes out. Ok, what happened? Was that me switching to a parallel world or something? I have no idea. Until I find another one and die and realize, oh, that's a save point. Maybe you could have said that.
And the dagger description says it can kill other enemies but says nothing about being able to cut through thorny vines.
Another point of frustration is that I can't look up and down to know where I am about to go. In other games, the levels are designed to be intuitive around that. But for example that water area that I fall down into and have to jump out of but don't know where I can jump up because there are blocks on the next screen up so I just keep jumping random spots hoping to find a hole. That was unnecessary. Or that part where I have to fall down a narrow chimney and just hope not to land on the fish below, because if I do the nearest save spot was like 3 screens away and I have to try again and again until I got lucky. That was sum bullshit. You lose a star for that.
The hit box on the dagger was kinda wonky. It would hit maybe 1/3 of the times I expected it to.
But, enough ranting. This game was a lot of fun, thank you for writing it and sharing it here. I enjoyed it and hope to see what else you make.
