IDK why but for me the game wasn't much responsive in terms of controls and I couldn't see any FTUE so I was unable to understand hoe to pick up gun plus as soon as I tried to go near shop- the game kept crashing. :/
Regarding, artwork - the character's art-styles matches (as per the screenshots) but more simpler and militaristic approach could had been better for aesthetic appeal and game-feel considering the game is being made for a jam.
I hope the game works for others and I hope you well! ^^
