The gameplay and visual is awesome
BUT STILL it's a buggy mess
you can't use mouse in menu for some reason
you can't progress at all after beating the first boss (due to the bug above)
you can't upgrade your gun, pressing R and R again will make you stuck only way out is to restart the game (due to bug above the bug above)

edit 1 : Ok so i played this game on another device and the mouse menu bug doesn't occur (prob because the bugged one is played on laptop with touchpad)
anyway here's more minor to mediocre problem with this game so it's prob not that serious
1) The image of the menu doesn't fit with the text (minor)
2) The crosshair being capped to a certain distance (minor)
3) The enemy at the top and bottom of your screen are more likely to see you when you don't even see them (medicre but it's pretty negated by the level design and a problem the dev can't do much about it so don't take this one seriously)

(Edited 1.5 ok just found this out literally not a minute after writing edit 1)
Pressing continue will break the game for some reason (got into setting menu with no "Back" botton (major annoying problem)

dev please fix this game is so awesome but the bug is killing the mood

Awesome game, this is a must when it goes on sale, on regular price is not bad

Obviously this is very much like hotline miami

The game is simple, but very fun, the enemy IA sometimes is kind of strange, but overall this is a very solid game, the gunplay is very good, the "realistic" style is awesome but at the same time it makes difficult to see were the shoots are coming

If you want a fast, and fun game, this is it
