For movement , i wanted to say, some movement camera like if you are walking ? but perhaps it would put gameplay problems.
The cursor have some alpha problems, and it could be bigger and red or green color ? why not ?
For traps, it could be some electric walls, or spikes on the floor, or a claymore ? Or a wall stone with a particular color , when walking in it would activate a trap on the rear walls !
Some ideas like that :
- Easy to use inventory with object displayed in HUD !
- Ennemis with a field of view : if they are not hit , and if the player is not in teh field of view , they can't see it !
- Big ennemies ?
- Critical hits , when you hit the ennemie from behind
or automatic silent attack with a knife (like Tenchu
game)
- C4 with distant detonator
- Claymores only touch ennemies not you and don't react to
you
- A fake holographic clone limited in number and per level
: ennemies would shoot it instead of you
- Flying ennemies in open levels
- Third person camera option ???????
Just ideas (i know it takes a lot to implement) !
Good job, keep it up
