Needs a bit more polish & attention to detail.
The snow level felt unfinished, and at parts disjointed, at the part where i jumped upwards the tiny cliff it didn't had a unified direction, so o had to frequently jump off in order to get forward. I also expected the ice tunnel to go somewhere inside, and it all felt pretty short.
Just as i beggined playing the next spooky level, as i enter the graveyard i imagined camera being directed at the gate and it closing itself (like a tiny cutscene). I also noticed that the bars i touched so far don't have MeshCollider, so i can go through them.
Also would be nice if you open-sourced it, there are pretty few decent open-sourced games to experiment (Hat in Time has modding support packed with editor and would be exactly that type of game that would be nice modifying, even though me modifying it would probably make it just worse).
