I like the way you used the fire sprite. The gameplay is a bit on the easy side, but I love the difficulty scaling with the slow introduction of new ways for the water elements to attack.

Wow, Mama Fire really saved me! I thought the game was endless.

I like how you made water elementals out of the same fire sprite. It is pretty hard, I only managed to get to 710 points. Bit of music and sound will really help. Good job!!

Hop to it and play this!  You'll get a real jump out of gameplay!

Honestly, this was a lot better than I expected.  Adding the different methods of how the water flames approach gives a lot more challenge and depth to this game.

I also saw in your source code that you built this from scratch.  Well done!

Notes:

• The HTML title for the project says "Jumper 1.51"

Super cool idea! I still have yet to beat it, but I made it to wave 5!

Fun concept, SUPER fast (maybe a little too fast?). Biggest wish for me would be have restart bound to spacebar or another key so I wouldnt have to take my hands off the keyboard to restart and i could stay LOCK IN! 

I had fun playing your submission and meeting momma! I'd be curious to see how the gameplay would change if you introduced variable height jumps into the game, but I agree with the other commenters that the difficulty felt right playing through each wave.

Good balance for the levels. Fun. The jumping felt good and predictable even though the jump was so high.

Good game! Highest I could get was 730. Nice job of letting tough challenges emerge from deceptively simple rules (spawning of water elementals).
