I got to wave 32 before realising how tiring it was and I got a liiittttle bit bored. Awesome game - but it needs maybe a few more milestones to reward the player for getting quite far. Maybe acknowledge it when they get through a whole mission without making any wrong keystrokes, or every 10 levels give them some arbitrary 'promotion' - something like that. Anyway, really good job.
