Wow I really loved this one! The minigames were creative. Nicely use of the theme. Beautiful pixel art and fun music.
The only negative points are that some minigame tips disappear very quickly, not letting me read them. Luckily, they weren't really necessary since most of the minigames are pretty intuitive. Also, I had the impression that the precision of the minigames to defeat the cockroaches is not so accurate and some minigames would be more interesting using the keyboard keys (like the minigame of pushing the object on the table).
Great entry! And Good job!
