Programming a simpel christmas game (CSS and JQuery/javascript)

I need you to program a small online christmas-game in CSS and JQuery/javascript I guess. I have the game from last year which can be seen here. (the cow is their mascot ;-) [login to view URL] The start (introduction text) and the ending (with the form) will be the same, but the game will be different. The gameplay this year will be controlling santa dropping christmasgift down different chimneys. (See the attached video for understanding) You will have 60 sec. or 10 gifts before the game is over. We have 5 different roofs which will be visible and rolling in randomly from right to left and you have to hit the chimney or the man standing on one of them. Hitting the chimneys will give you from 0 - 2 points depending on the roof. You will be dropping a gift by pressing space and the gift will fall half a second or something so you have to drop it a bit before the chimney is beneath you... we will have to test how this work. At the same time we have two different backgrounds (mountains and woods) wich we also will move from right to left but with different speed. After end game (if you score more than 3 points) you will be able to fill in a form like the one we have today. Also we would like to send the formdata to a Google sheet document, containing all participants with date, point, email, name and company (the example from last year is right now sending to an Acces database) I will be delivering all graphical content used in the game as SVG or png or whatever you prefer. Any questions feel free to ask
