Brilliant, just brilliant, well done!

pretty fun, works well

Nice! Stressing for me... rushing is not for me. But the game and the idea is pretty nice. I had some sudden stutters while playing the game. Could be my PC that is quite old now, I do not know. It would have been nice to have a look at the code.

Man, watching the "wave" approach from the left side of the screen instantly reminded me of the 2011 Japanese tsunamis.  so, that was kind of an interesting mechanic.  controls were relatively easy to figure out, I liked the background palette transition and character animations.  Just need a little more to do.  not bad!
