Thank you for you appreciate and suggestion! I'm still update the game by far, my idea making a kind of climbing-tower game, you can buy update use your coin(life). I was already design 7 type of enemys and one level, the game goal is to beat the level and meet the final boss. I don't know how to fix the pixel-perfect scale problem on the web edition, on my desktop edition it is *1/*2/*3 or full screen scale. I don't know how to achieve this in the itch internal game browser(seems it's fix size) so maybe I'll optimize for the web edition manually.
