Pretty interesting, the main gameplay of shooting and running worked really well
Some things I'd really like to see improved is the way the story is incorporated into the game, I didn't understand what was happening until I read the description you posted here, also I think the bosses are a bit too easy? when theyre in a corner you can just fire at them until they die hahah also the shake effects were a bit too heavy I think, i got a bit dizzy near the end...
Besides that I did enjoy the game, it's a simple fun twin stick shooter
