Good game, but a erase tile button would be nice so I don't have to reset the level if I place the wrong tile

Hi!  I played your game in the browser.  I really like your low-poly isometric art and your game's music.  

I had a hard time understanding the game's basic mechanics, especially why I had to pay money to do everything.  It's not a great feeling to have to spend currency to do literally everything in the game, even the most basic action of placing a tile.  I struggled a lot with the UI, especially with not knowing which tile was currently selected, and having to use the number keys to select tiles.  Overall more player feedback would be great.
