It works smoothly! The only error I got was at the end: some words looked a bit scrambled, but otherwise it worked fine! 

I was a bit confused at first because the player looks more suited for attack than defense (talking about its shape), but that was only at the beginning.

I got around 75 points! :D It starts easy but soon enough it gets harder (that's nice!).

Is the mouse movement slowed down any? I kept thinking I had a hair my mouse's laser or something, it just didn't feel 100%. I think I scored 80, not sure. After it ends, the text all overlaps and you can't read it.  But you definitely have some collision issues once the drop speed accelerates, passing right through the barriers. Look into "swept" collision. In your case, a simple line-line intersection test would do the trick.

Hello!
Thanks for joining! The entry should be a nice remake! The explosion sound effect.......so good!

I like the hand-drawn art style.   If you want to take it further post-jam, it might be nice if the explosion animation was also hand-drawn.  It might also be nice to have some variation in the gameplay, perhaps managing multiple shield layers rather than the single horizontal row.

I managed to stop at least 80 bombs from the flying saucer, but once they started falling too fast, they just passed through the thin wall like neutrinos ahahah

I also realised that I could cheese the game by holding the left click, but then the saucer got mad & started spamming bombs faster than the speed of sound

Might be worth adding a bit of collision tolerance when things speed up :)

The colors in your game are so well picked. They're easy on the eyes. Nice  work.

This seemed easy at first but man did it get hard. I liked the colorful graphics and the controls were pretty responsive. I think the gradual difficulty progression was done just right.
