For the most part I'll echo the things everybody else is saying:
Excellent art and polish, initial trouble with controls, fire does too much damage, chests are finicky etc...
Personally I never figured out how to air dash so it might not hurt to have the relevant key combination
as a detail in the inventory page for morons such as myself. Speaking of the inventory I wanted to suggest
either making the chests specific colors based on the loot contained therein or making the text of said
acquisition colored based on the type of item it is. Every time I picked something up I needed to break the pace
and go to the I screen to even determine if what I picked up was a technique or a weapon or anything else.
Besides all that, you got yourself a Twitter follower and I'm eager to see how this title progresses!
