its good, but a little too hard.
i have played this game with friends and apparently im really good at it, but I think you should do 4 main things:
1. Less of those fucking red pterodactyls, ive had times when id see like 4 of those things on the first level of medium mode!
2. make it on the twin peaks scenario so a stream of shit isnt constantly parading on your face, that shit got old fast!
3. debug it some, i keep falling through the floor all the time, its pissing me off when im on level Apocalypse about to finish the game on hard and what do you know, im falling through the damn floor, there goes 30 minutes + of hard work.
4. make insane less insane, i can go full stats through the first level on insane without making _any_ mistakes and using sprints when available. and that F-ing doom will be 3 seconds behind me when i finish! that's beyond insane, THATS PSYCHOPATHIC!
other than those obvious complaints of mine, i thought it was fun and ive had so much fun playing it.
