Decent Game.
The art is very clean and professional. The gameplay is fun but it ends at about the 3rd or 4th level.
As stated before, upgrades aren't balanced with the enemies faced as all you can upgrade is rate,damage, and multishot. Otherwise, upgrading money magnet seems a waste since beating a level gives you all the gold on the ground anyway.
What would make this game better is an indicator on your robot when you're damaged, since playing with the sound off you cannot tell if you've been hit without looking at health.
Everytime I kill the last boss it gives me a token to sell but then it doesn't give me the badge for killing the "Shadow Boss" is Shinjid not the last boss?
