This was pretty fun! There's a lot going on here, much more than in a regular SHMUP. The gameplay has a lot of facets - hunting for seeds, defending the plants, and hunting down the space bugs. It plays very well into the theme of recovery too. Well done!
It is a bit awkward that the plants block your shots. Maybe that's just me being bad at this sort of game, but I found that a little annoying and frustrating at times. That's really my only complaint, though. This is a fun game, and it executes really well on the theme.
