The game is good but there is a few flaws
-First one is a control but : When you crouch and you turn to face the other direction your gun still fire in the direction you originally crouched in, forcing the player to get up to crouch again in the right direction. In situation of life or death it usually means death and once of the main reason I couldnt complete the story.
-Second is a design flaw, most of the time the presence of boxes means that there is an incoming ennemy. All I had to do was to spot the edge of a box and shoot immediately, killing most of the ennemies before they would even spot me.
And here are some more minor flaws I spotted :
-Putting computers everywhere when you show in the tutorial you can interact with them is kind of misleading, you should make a particular sprite for the computers the player can actually interact with.
-Sometimes ennemies that spawn through scrolling disapear if you scroll back far enough and never comes to you.
-Walking doesnt seem to help catching the ennemies by surprise but maybe it's me.
Overall the game is pretty difficult, the healf or armor drops arent very present in the first levels and the bug make it all the more frustrating. maybe an option to retry a level would be nice instead of a game over screen and then everything to complete all over again, the levels are rather big so it's quite tedious to do them all over again.
