Overall really nice game I really love the shooting and the shop, but sometimes it can feel rather unfair to enter a room and immediately get bombarded with 2 shotgun shots in the face. Perhaps it would be even better if you could wait until the player enter a certain are in you room and only then will the enemies stat shooting. Also the enemies always shoot at the same time would be nice if they had a different timing between the shots and generally wouldn't aim at the player but where the player will be because dogging right now is rather easy as long as you are fast enough.
Besides that tough really nice game and especially well done for a 2 weeks time limit.
