Neat! I like our variety of monsters and having two different styles of attacks, it was fun experimenting what worked best for each one. The sound for a new wave gets cut off pretty regularly by your attacks, it might've been worth using a shorter music cue for that and/or adding some visual change to the level indicator (making it blink? shake?) to indicate the start of a new way. Oh, and I love getting to see the sprite pre-post frozen, they were all v cute ^-^
