This was a great entry. The art is beautiful, and it feels very polished. Brutal difficulty, but not in an unfair way, just in a satisfying boss battle way. Could easily be expanded to a longer game that ends with a battle like that.
The art has great style, except I'd often lose the dark character silhouette on the dark areas of the mech when trying to jump over bullets.
I never did beat the mech, but at least I can see the good ending on Youtube....... Oh.
