Not very satisfying gameplay, but good graphics. Flashlight element is not in use.
I would suggest reworking :
1. Add measurement scale of jump power
2. On 1st level I had troubles with jumping, because it wasn't obvious that you can start jumping when players model is not on platform.
3. Gunplay is worth reworking. Not interesting at all.
4. Add lives
5. Movement:
- add WASD
- It's strange, that movement is on keys, but jump is on z.(↑)
