Dude! Awesome game! Super high quality stuff! I love all the cool pixeling, attention to detail and style. Can't wait to see it fully released!
I have a few suggestions you might make. Your crosshair is small and red and a lot of your environments are orange and red. I suggest you make the cross easier to read in the hectic chaos (or if you ever update or make RELOAD 2, keep the crosshair color in mind). It's also a little difficult to read where the enemy attacks are coming from but that's just me. When I played it a second time on hard, I did notice them more though. Maybe you can have more of a power up or build up and aiming to the damaging blows. Almost like they're winding up for an attack. Just a suggestion.
Your motorbike henchman looks great! Keep up the good work!
