This was a fun little engine building game. The AI was frustratingly good at beating me, and it felt like it targeted my money blocks. Once I got my economy running, things went much smoother, but there were still some tense moments before winning.
With a little more polish, especially to the movement of the paddle, and maybe highlighting which block you have selected and/or showing exactly where the block will be placed with an indicator, this is a really solid game!
