this demo is great! super fun and loved the music! few things to note,
a few stutters while loading into a new level, nothing crazy but somethihg to look into.
i didnt like how the explosive barrels could lock onto other explosive barrels. was abit annoying when i aimed for the enemy and it locked onto a barrel instead.
i think it would be cool if you could knock the bad guys into other bad guys, even if it didnt do any damage, would be cool to see them fall over each other!
some instructions are unclear, took me abit to understand how the true/false thing worked and also was unclear how the making doors thing worked.
other than those points i think you have a great game under your belt and will check the game out when its fully done!
