Fun and simple arcade style game. Had a good bit of fun with it. The graphics and animations were quite good (I love the slow down and zoom of the slash). The music and audio also felt really nice as well. :D
Feedback:
- The lives system is a little bit confusing. I realised after a bit of playing that the lives are more there for if you miss a dummy, and not there for the spikes (which more often than not, insta-kill you). I think the solution is to either get temporary invincibility after hitting a spike, and only lose one life OR replace the hearts with pictures of the dummies, and make the spikes properly insta-kill you (not drain all the hearts really quickly).
- Only other feedback or idea would be to give the player a multiplier if they hit multiple dummies at once. This encourages more risk/reward gameplay, and adds another layer of skill ontop.
Good job overall, keep up the great work. :)
