Frogger Added

I've now completed the second "Game 3" of the project. It took a while (between the holidays, spending time with family, and a little bit of procrastination), but it's done. Also updated the main menu (hopefully for the last time), and I think I fixed how screen shake works.

I'm getting a slight bit more confident with making art for these games; while I'm still relying on Kenney assets for some things (sound effects too; the ones I chose aren't exactly the most cohesive, but oh well), I do like how the log in particular turned out. Jumped through a few hoops to make sure the logs/turtles mesh decently with tile-based movement, and figuring out certain aspects of using a tileset was a bit confusing, but overall I think the game turned out alright.
