After playing for a short while this amazing PvZ spinoff has a lot of potential, I really do enjoy this fun Rogue-like experience for your typical PvZ gameplay.
I am a huge fan of the unique aesthetic of the game, I do hope that future releases will add some music.
MY SUGGESTION for Music impimentation: is that I've noticed the game has a progress bar, what would really fit this game similar to PvZ, is that the longer you survive in a level, the more instruments are added to the music starting pretty basic and by the end its fully pumping!
I would suggest for future releases and updates to "Zip/RAR" the entire file for easier download and as well for easier way to play :)
Either way keep up the great work! Cant wait to see what you come up with next :)
