Ok game
To me this is game that's fun for 5 minutes, but then after that it gets way too repetitive. There could of been a lot more enemy variety, for example those quick flying robots were different types of enemies which needed a different approach to kill, that was nice but there should of been way more variety.
This is a fun simple game, but imo things could be done to keep it interesting for a longer time. Change up the music (which I hated and I don't even have a problem with metal music), change up that old tired street background, add more enemies, maybe give them a little more personality. Instead of seeing the same old enemies, make each one a little different like instead of just idiots, have old people, red haired women, fat men stuff like that.
