Great work overall!
Theme:
“My super planned murder can’t go wrong ? Wait ?”. Good take! IDK how but maybe you can push this idea a bit further with things that change your plan.
Art:
Good idea to have such a simple design for the target vs other people. I think it’s maybe lacking a simple background
Gameplay:
IMO this is where you have the most positive and negative things…
Positive: It feels great to fire, the sound effect, the bullet animation and the announcer at the end. Nice!
Negative: the mouse movement is too slow, it feels sluggish. This can be a bit frustrating as you lose X seconds every time you replay a level. This combined with no level selection hurt the replayability.
Overall: Nice Work !
