The theme sounds familiar...
My very first Ludum Dare was Ludum Dare 27, and the theme was "10 Seconds". Almost 10 years ago! Time flies! So I was thinking, why not test my skills a little, and re-imagine my very first Ludum Dare entry.
My skills were basic and the game was basic, but I was proud of it and it's meaningful as a first entry :

The new version is totally going to blow it out of the water (hopefully) and will be nice to see how many skills I've gained since then.
Good luck y'all!
