This is an impressive entry for a first game jam. Well done. I also love seeing other Godot games! Welcome to the club! The SFX and music were good. The Gameplay was very interesting. Creative use of the theme. I was impressed how you took the bats with no animations and just had them bob up and down a little. The block tower was creative.
The block towers were cool, but they were really finicky. Especially when trying to hop up pumpkins placed over the houses. I didn't get the point of the yellow cube. The game lagged so badly when I got to the maze that I ended up quitting. (You may have a memory leak.) It was a bummer the music didn't loop.
Overall really good first game.
