I honestly didn't feel like it was slow or anything, the life limit meant I was being careful even when things seemed "easy" so there was some solid tension throughout, even when replaying the same levels. And it had that, like, "this level was tough before but now I can kill em all in one tap, mwahahhaha!" vibe to it.
With that said, I do hope that you make a post-jam version or continue developing it. I really enjoyed the game :D
