A knock off of robokill
Sorry man, i can see you put effort into this. However this game is far from unique. If robokill has a copyright, then this is definitely breaking it.
The game itself is also downright unpolished. Movements are glitchy, you get caught on objects and the pace is gureling and uneventful. Bullets seem to pass through enemies, the rooms all look exactly the same, and AI movement makes no sense. The weapons and upgrades are even complete copies of the robokill items, while somehow being less appealing and less fun to purchase. I found myself bored quickly, with no interest to continue.
I also found the fact you were trying to get money off the game appalling, it's like adding insult to injury on the original creator.
You should respect your peer flash-creators more, just because they put hours of effort into making a unique game, does not mean you have the right to make a cheap copy, then attempt to sell it.
If this game had no "Coin purchased" Components, it would have received a 5-6
