This game is great. The weapons feel great to use, the enemy designs are fun and can range from hilarious to creepy, and the secrets feel well-hidden enough to feel fun to discover, without feeling cryptic or anything. I feel like there could/should be checkpoints here or there, but I suppose that's also what the save and load feature is for. The one thing I would suggest changing for sure, however, is the weapon switching. I feel like scrolling the mouse wheel, or cycling through them one-by-one with Q or E would feel better than trying to reach out for the number keys. Cheers mate.
