Nicely done on this entry, i had fun playing it! Youve definitely got the core elements of a fun top down arena shooter game, with cute characters and weapons. The shooting mechanic was fun and running around the map dodging enemies was also adequately challenging. I had a bit of issue on the border where my character once went off border and then i couldnt get him back because i was surrounded by enemies :D
One suggestion i have is that adding more visual feedback like particles effects on hitting of bullets, or flashing of the player when hp reduces would go a great distance in adding more fun to this! I would also have liked to see some player powerups (maybe theyre there later, but could be showing up from the first level itself) Overall well done on making this game, and i loved the intro also :)
