- Is the mouse sensitivity supposed to default to the lowest value?
- Did you break the weapon swaying? It's extremely slow now.
- The level is too dark and has too little contrast. I can barely see anything when playing during daytime. Make sure walls and floors are never the same color.
- Steal Serious Sam's enemy health bar crosshair.
- The jumping doesn't feel good. Reduce air control and make it give you a small boost in horizontal velocity.
- The attack range on the melee enemies doesn't match the sprite.
- Level 2 could really use some signs.
- It's so dark the grinders are barely visible. They should also move faster to make it obvious they're a hazard even without the posters.
- When the player gets a new weapon, put him in a situation where he needs to use it right away. The canister rifle penetrates enemies, but the first enemies you see after getting it are two fat guys standing side by side.
- I still think the fireball enemies should never be put in cramped rooms or in positions where they have line of sight of the entrance to the room they're in. They work well in open areas as a low-priority target that restricts your movement, but when they block your movement entirely, they just waste your time. Also, they need other enemies to work; don't have them on their own.
- Died to melee enemies appearing behind me after picking up the red key on level 2. They need to have a different alert sound from the normal grunts. Also, footstep sounds.
- Getting shot while you're hanging from the hook feels cheap.
- The assault rifle doesn't feel like much of an upgrade over the dual pistols. It could at least have better accuracy.
