Hint: Don't wait until you see the enemy ships start firing as soon as you can. Love the concept of upgrading everything, ... uploader, ... graphics and of course your ship. Thank you for a fun game.
Got the three badges, but the fun went out it when it was too picky about placement. The grenades seemed to be going in the right place, to the millimetre, but often the effects of the blast are not the same as shown on the walkthru.
Really nice game.
Small note ... if you are wondered why you are not getting your achievements, try Save and quit ... to keep your progress, then reload the web browser page.
I like the concept of the game, BUT, the wall of atoms interrupt is NOT instant cast as promised against The Great Psonic ( second boss ) so even though i have no problem interrupting slow casts in the arena, against this boss it does not fire at all, against his heal.
Would it hurt for the difficulty to increase at a slightly slower rate? With slightly different sounds I can see this being a relaxing game with a pleasant challenge.
