Wow, what a fantastic little arcade experience! Feels just as fun, juicy and addictive as any of the classics like Tapper and such, and I enjoyed the simple yet fast-paced typing action!
If I were to have any complaints, it'd be:
*Sometimes you get unlucky enough to have brothers constantly getting sucked up and you're just kind of sitting there twiddling your thumbs. Sure you're gonna get points for it, and perhaps it's necessary as something to keep you on your toes, but still, kinda wish the algorithm always keeps me in action, or maybe you could press some sort of button to push the brother up faster, like how you can stack tetris blocks faster if you want, haha.
*As the waves go on, there end up being a lot of UFOs that blow up at the end and it can get so loud it hurts my ears. Might be nice if the programming was changed so that if multiple explosions (or sound effects in general) happen at the exact same time, it just plays one explosion sound effect.
*And the biggest complaint being that I wish it kept escalating even more with harder words and more elements to look out for to keep you engaged and fighting for your life!
