Nice game with cute style art. Some few things you might consider...
- Good to have all controls with mouse, but perhaps not for the Big Lazor which is activated by double click. Once there are bullets all over the screen and I want to get rid of them by using this special, to double click make the ship unable to move for 0.3-0.5 second and that very sharp moment makes the ship vulnerable.
- The heart and special containers are easy to understand but what are those red and blue containers?
- Would be good to know where exactly the hitbox is.
- The main ship and the bots have pretty much the same color tone and being on the same layer. There were some few times that I get confused that the bot is ship, so I move the bot away and the ship got hit by bullet (perhaps this is just me?).
