Thank you for playing!
The flamethrower is a brand new weapon that wasn't in the previous build. I'll try experimenting with a few different colors for the UI. Originally it actually was green but I found the white on black color scheme to be more readable on different backgrounds. I could also try increasing the shadow under the UI, it's only at about 50 opacity.
I thought about having the pilot on screen permanently but I felt like she took up a bit too much space on the UI, so I went the Bulk Slash route of having it open and close only when she's talking. Same reason the quips are also very infrequent (if you saw any) - I'm slightly worried it'll outstay its welcome if it comes on screen too much, especially for a full length game lol.
I like your idea of a linear level like the highway scene from GITS; honestly the level design and mission structure has probably been the biggest challenge so far. I was thinking of doing five different biomes/areas with five different types of missions as someone on the previous DD suggested. I would really like there to be more variety since as you said even with different weapons and upgrades it'll just become repetitive. I might need to recruit some outside help to really get that part down haha.
Thank you again for playing and the feedback, it's much appreciated!
