Hello again! A few more updates.
Additions
New gun! Gold Revolver. It's just the regular revolver with a new sprite, except it has infinite ammo. Expensive in shop.
New passive item - Steel Insoles. When you have these, you're invulnerable to floor spikes. You can walk right over them.
Changes
Increased the area near doors where enemies can't spawn. This should help reduce the chances of running into an enemy immediately when you enter a room.
BugFix
Wimpy, the new enemy would change from blue to green when an explosion launches him towards the screen. Now, he stays the same color.
Compact pistol can now show up in the shop. It was dropping from chests but not available in the shop previously.
