I remember this one!  I saw lots and lots of clips on the discord server!

The first two times I played it, a small bit along the bottom of the screen was cut off, so I did not see my level and how much health I had.  By the third time, I learned that paying attention to the game's page yields important information...  Nice to see the player was rewarded for surviving as the game progressed!

Notes:

• Would have been nice to see a final score.
• There were times when staying still on top of enemy did not result in taking damage. Something to do with when it moves, it seems..?

Nice one! I had fun playing through several level, though I couldn't make my way past level 3 (most likely a skill issue). Great audio here, too! I was curious about whether or not it was intentional for the viewport to be doubled/scaled like this with a smaller version of itself in the center? It made things a bit confusing at first until I realized I was looking at the same viewport, just with one smaller version in the center of the larger version.  In all cases, thanks for making and sharing your  game!

I don't know whether the game is endless, I reached Level 8 on my last try.

I concur that the music is great. I think due to the visuals the game doesn't feel that much like a NES game to me but more important it's fun to play, finding a gun and clearing the screen is satisfying.

Thanks for sharing!

Not too bad, but could use some indicators of what's going on, like a text box that says "Survive!" or something. 

Bugged out stuck on level 0 on the wasm (browser) build
