Gameplay: it ended up boiling down to "stand in place and shoot through the well". i like that the crabs rapidly ramped up their assault. the thing i like the most is that the game waisted no time throwing me into the thick of it.

Graphics: the crabs defeat animation was very nice, very poofy. everything about the sprite work was clean. i liked the weird moon/planet you see from looking straight up. the only real let down here is the very plain environment.

Audio: the music and sound effects where very solid, i have nothing special to say about them.

Theme: using the power of the wish orb to wish the crabs away, very fine. tho now im wondering about the lore here. whats at the bottom of the well? why has it aggroed the crabs? why does the well have a tiny little face? what does the wish orb have to do with all of this? very nice stuff

Survival of the fittest wishing well.  Damn solid effort, for sure.  Too bad it doesn't make my wish and make all the bad guys go away.

I had to load it up three times before I could play it and had trouble with frame rates as the game progresses (which is a problem I ran into when building my own fps from scratch; this was due to the game trying to deal with unknown values which html5 canvas absolutely hates).
