Mostly-Builder

My most recent game will probably never be finished to the point the other games have, but that was not really an issue.
I gave the player two buttons with the option to switch from a destroy mode, and a building mode.
I was able to limit ability to build to 300 pixels from the character, then I drew a square under the cursor where the block would have been placed only when you would have been able to place blocks. This made it far clearer that you could place blocks, and when you can't.

I wanted to try to use a visual technique I found to make everything appear to have depth.
The game only features a moving player and the ability to place and destroy blocks under the cursor

I used larger castle-like blocks as a proof-of-concept. The towers where large enough that the player could be hidden behind them

My original intent was to make the game being far bigger, But I did not want to leave another project unfinished.
I wanted to make the room size a lot larger, to make a large random world to explore, with the screen only showing a little bit around the character.
I tried to create an AI system to populate the world with zombies, or a similar obstacle, but i decided the building was a more important part of the game.
If I had more time, I would have made trees, and rivers, with a rudimentary crafting system.
