This is meant to be constructive criticism. Since you added a poll I figured you would like some.
First, to me this is just a jumbled mess of overkill effects... (imo)
To improve you could tone down the lag causing (overkill on explosions). Also, work on the Frame Timing to make it look right... Like some skill the effect goes too soon, some too late. One I seen you had it timed right.. Next, work on actually damaging in the effect area so it's functional.
I did like the fact you used those big bomb things in the Kobold levels for explosions I never thought of that.
