Every game doesn't need to be mouse aimed
HUNTERS GENERALLY:
I still don't get what's the big fuzz about the graphics: even if they are simple I think they work perfectly. I think the animations in the cinematic scenes are also quite nice.
What I actually understand better are the complaints about being able to shoot only in the direction where one is walking towards. Sometimes that can feel frustrating, but that's how these kinds of games work - for example there are still new incarnations coming for the Contra series and they still work in this manner. I wouldn't want this to have a mouse aiming scheme, since those games have a totally different feeling to them, and this kind of a control scheme isn't just unambiguously inferior.
Still, there are things to consider to improve this kind of a "classic" control method too. For example there could be a 45 tilt button so that one wouldn't have to constantly move when firing diagonally. If I remember correctly Super Metroid for example already had these kinds of controls. Secondly: if there are bosses or other special situations where the enemy is constantly on the other side the controls could change in the way that one couldn't shoot in the wrong direction.
STAGE 2:
I think the second level was more repetitive than the first one. Fighting all those animals and avoiding those spikes got a bit tedious - and the turtles were annoying. The challenge level was still good - not too easy, not too hard, although I think I prefered the bosses of the first level. That's why I'm giving this a lower score than what I gave to the first stage. Let's see what the next one will be like.
