I'm sorry you had many troubles trying to play the game. I'm not sure what caused it, so I can't be of help unfortunately. The progress bar is how much harvest did you gift to the statue by interacting with it, on top-right of your farm. I wasn't able to implement proper UI on time as well...
The rain is constant in the game, storm is represented by the lightning strikes that occur every 25-45 seconds. You have to hide from them in your tent and continue working while they aren't present.
Thank you for giving it a shot even though you had many problems!
P.S: I also seem to switch the pumpkin and watermelon seeds by accident haha, sorry about that.
