A Good Start
I noticed that I wouldn't stop until I had finished. But here is what you could improve on:
Make it longer. There was only about three puzzles and two items to pick up (although i wonder why that item that opens a certain door didn't appear in your inventory...). I hoped that you could have made a puzzle where you had to use items, or even the possibility of combining items for further use in the game. I liked the difficulty of the puzzles though, don't change that at all.
There was too many rooms that were useless. Near the end your just advancing from room to room and there was nothing in the rooms. I think you should get rid of those. If you were trying to create a dramatic experience near the end it didn't work. But at about know I'm wondering if you added those rooms because of a random chance that a monster would appear...
Items. The weapons and armor cost way too much. Why buy a 50 credit weapon!? It only increased it by 3 damage. the first two weapons should have cost only 10 credits and the third 20. But the KF "betteries" were a good price and the grenades and those health pack things too but the weapons were overpriced
On the good side:
The credits were awesome. it was like what they do for a movie. Keep it up!
That RPG feel in the game was a nice add to normal point-and-click games because it "added flavor" to it, you know, something new. And the credit and buying new supplies was cool, but Wiley should have been available to buy from at any time, instead of having to go back all the time.
Well, this has been pretty impressive, considering it was your first game. If you improve I believe that you - Hyptosis - can get famous of your work!
