It's spelt "Reliever", and please make it differen
Ok, but you really need to make them different from the others. Here's some things you can do:
- Movement through levels
- Reload Function (able to see it graphically 2)
- More enemies (more as in quantity and types. Maybe you could redesign your old ones and put them all together, and make them hurt you)
- Different sides to appear from, rather than just from the left side
- More weapons, not just one, and if you do only have one, animate it better (graphics, bullets fly out of side, muzzle flash)
- More gore and blood
- Better sounds
- An ending
- A health and armour bar
There's suggestions, try and use all of them. Otherwise fairly average work.
