my first review score was worst but i have changed my mind to be better once finished the game.

even though doubtful design like sharing ammo between bullet/grenade, linear map structure (less adventuring feel),  and a bit slow pace in couple of starting levels.

the good is

• the game held much longer than i expected
• map becomes intriguing on proceed in regard to design itself and story telling
• unexpectedly AI works well
• handy map view
• level codes to skip/keep levels

overall, i can say "it was fun" to others.

**there are notable graphical glitches/garbage left when destroying objects. i don't know if its issue of my emulator side or not, and has no impact on play anyway.
