Hey Asim, here are my thoughts:
- I really liked this game. Very refreshing amongst the hundreds of puzzle/platformer games.
- The style is executed very well. Art and sound go together nicely.
- I would add a minimap of some sort so the player could navigate through the dungeon instead of running around like a headless chicken.
- The music and SFX was defaulted to 0. I would just make the default the half of the slider. I thought at first it had no music and only heard it after reading comments and booting it back up again.
- I would go for an ammunition counter instead of a fill-up bar.
Nice little game. Although the rewind did not seem usefull for me, it still is a nice retro 2.5D shooter. Good job.
