Wave 21! Supper addictive, simple and fun. At first I was it was some cookie-clicker type of game, but reality was much better. It's one of these experiences where each time you firmly believe that you can change your strategy to last even longer next time.
What was the "boss" part here? I got "on the edge" feel from it for sure - these little pockets of time to build defenses I definitely felt on the edge.
- This is a nitpick, but from my playthroughs, it seems to be the case that once you build initial 10+ factories, you won't need to touch them ever again and just continue building defenses around the base round by round. I feel like there could be something to balance that idea - for example factories could be more expensive, giving a player to perhaps be more strategic in how they spend their resources.
- Also, it seemed that I was clicking like an insane person to build as much as I could in each pocket of time. It could be nice if I could just 'draw' the lines of spaceships since later in the game it seems that whoever can click their mouse fastest - wins. Drawing would allow to come up with strategic shapes easier too.
