Hiya! This is minimal and I only had patience to design 3 levels (although adding your own should be pretty straightforward), but the challenge in itself was very fun.

While I do think this can be golfed quite a bit more, I am pretty satisfied with the ratio of code to result.

Golf score is 3048 bytes (1187 level data + 1843 js code + 18 html).

There seems to be an issue with the third level, I'm hitting an invisible wall right above the hole :(

My bad! This happens when the initial window viewport is too small. Actually fixing this removes 98 bytes from the solution!
