Wow, this game is unbelieveably well polished. This feels like a full release!
There are no real things I would suggest, maybe making it a little bit more clearer wich bullet you're using, as changing it in a hurry can make it hard to pick the right one.
The music and sfx are also very good and the artstyle looks professional and appropriate!
Very fun and addictive game to play when theres nothing to do at work :D
I do have one more question, are you Manish Vyas, or just a fan? (Or someone with a very similar name?)
