ok I was lucky on the first play though got all the way to the boss. If level 4 what I think it is I looked around there for a 10 second then saw the answer. this boss is harder yet I figured out a plan.
I like the fact you have check points but the need for them till the end is minor for thse versions
I saw by your responses your working on full length game good luck.
Ok I'm going all out here since this is the latest one with a LIST of suggestions
Add P for Pause
More weapons
Enhance the combat system.
Sure things get a littler harder but if you do the above I feel you can scale up the difficulty more. I feel games where you zip all the way to the boss then spend all your time on the boss for that level lack that mojo. sure the first level should be easish but make it harder or get boring.
pus if you ramp up more the boss that takes a while to kill semes to to go with the flow of the game better.
Ok Contols i'm only going to cover pc sicne that what use.
WASD (this goes with my next suggestion) but I like the fact you can change the buttons.
Should make so people can use mouse to do attacks, even if you add guns it still works. If you ever decide to use a gun and ammo R for reload there is never any other choice (blame res evil)
Monster list Ok you can add more different type zombies.
Since you going with a horror theme goblins, Werewovles, ghost, demons,vampires, and mummies. also witchs could show up more often and drop various things other than gnomes, like dolls, goulies, gremlin, Imp or various little monster. Troll could be added too either as a small dropable or a big thing.
Oh I almost forgot character choice be able to play as guy or girl.
