Thanks, yeah the terrain texture we should have put a little more work into, the idea was to cover it all with grass but that KILLED the optimization (even on higher end computers) so the texture didn't get covered up as much.
(Spoiler paragraph) As for the house, you're actually supposed to continue up, past the well, then there is a hole in the ground. If you fill that hole with a rock your character can pass over it. From there you'll find a small cave with some trees and another rock blocking it off, break the trees and move the rock (or break the rock too but in this game having more rocks is generally better) Inside that is a key which goes to a gate nearby. Open the gate and you can continue to a new cave that leads you to the next level.
Unfortunately for the version that was submitted to the jam we forgot to include the json with all the dialogue which is why you see none on the first level and since the dialogue that plays at the end of level 1 is also missing it does not load level 2 correctly. Same thing for level 3. We plan on uploading a post jam version later with that bug fixed and a few others as well.
Also, I too am really impressed with what we managed to do in the time frame. My team really did a good job. I also got 4 hours of sleep during this whole thing because of how much work we had. lol
