Here is my first build of my frogger game for the challenge (make sure to download the game rather than assets pack):
After starting early last month I've been put on hold most of this month due to attempting to move house, so I've had to severely cutback the features, but I have managed to pull things together to make something playable. Still lots I'd like to do to improve once I have some more time on my hands.
I spent today putting together 14 or so levels, it should be reasonably challenging, and enough to spend 20 mins or so on, I can complete it.
Let me know if it runs okay, there are Linux64 and Win32 builds. I tried making an Android build with Godot 3.1 Alpha but no luck so far, it crashes on running, maybe I can change some settings in Godot and get it to run.
Also the sound is a bit broken, the 3D listener is broken in Godot 3 currently so I had to bodge some 2D sound until they fix it.
Cursors to move and TAB changes camera view. Incidentally, though the game is usually easier in top down view you can theoretically complete it all in closeup view, if you want a real challenge!
