You really need something where if the cat doesn't get a piece of sushi after 15 seconds or so it starts downsizing. Infinite loops happened way too much, especially anytime there was a rotating beam next to a wall.
Another thing I feel I should add is that the game has cascading lag issues over time. Make sure the data for the bullets, tanks, and life powerups are all properly freed up afterward.
The game is pretty awesome. The only complaints I have are in the presentation -- if you set your quality to Low, every snippet of dialogue and every stage reset brings the quality back up to High. Furthermore, the cutscenes lag significantly worse than the game despite being visually simpler. Other than that, the game is fun!
The grind is so much worse than the first one. I get that you shouldn't get the cool stuff right out of the gate, but you shouldn't have to spend hours before you can do anything interesting either.
Nobody's going to pick anything other than the easiest bow setting. Really, you have to unload so damn many arrows in this game that having to carefully slingshot each one is a lesson in raw tedium. Other than that, nowhere in the game does it explain how to create and manage units -- they just kinda come in automatically.
Fatal bug: if you earn a key and logout or otherwise quit before placing it into a lock, the key is gone when you come back and you can't re-earn it from either pre-boss level.
The lag feels like you're not properly getting rid of objects once they're gone -- make sure you free up the memory for a projectile or monster once it's destroyed.
The hit detection is pretty sloppy. I'm being hit by things nearly a quarter of the way across the screen. Furthermore, the damage on bosses' instant-fire laser beams is a little ridiculous given that there's absolutely nothing to telegraph that they're about to fire or in what direction. Fighting bosses like that is basically blind luck of how often they decide to use that.
So...the game opens up after the into text, and nothing actually happens. My character never appears, and clicking any of the things on the bar results in "Close Window First". Did you beta this at all? o.O
