The UI is very... bland. Everything is either the same colour or has the same colour scheme. Things need to stand out or the player will get confused when browsing the different menus.
A few examples;
-I couldn't tell where I was on the minimap. The orange colour around the corners does not make it stand out. (Everything is goddamn orange or blue).
-The scolling buttons (which are huge blocky squares with arrows) don't ever change appearance. I'm just constantly clicking them.
-Most of your UIs are just floating boxes with either texts or images. Draw some lines or contrasting boxes to show me which buttons are related.
-Try to add a bit more flow to your camera movements. During battle, having the camera suddenly warping around can become confusing.
Some of these points may be hard to interpret (as in figure out the problem and then finding a suitable change, also the fact that most of these points might seem useless to other readers) but making these changes will improve the game.
Alright, so, CAN YOU KILL THEM ALL WITH ONE BULLET?
I've been doing level one for about 30mins TRYING SO HARD to get it all in one kill.
BTW I was close.
