I like the graphics. Maybe add more enemy types and change their bullet colors?(also, the final boss's central weapon could easily be made to look better, just give it a charging orbs effect and make it a forward firing laser. rather than just an extremely fast bullet. Overall it's pretty good, and I have high hopes for the sequel.

i usually dont hate on games for being too hard, but this game is really too hard.

This is a good game, i tried this game before on a mobile phone and this is like the same :D

Made the game much easier so players can now reach the final boss and see the ending.

Not bad, but a few constructive criticisms:

You need to think about how the various objects contrast with each other. The player's ship, enemy projectiles, enemies, and your own projectiles should all have their own distinct color scheme(s) that don't overlap, so that the player can see what's going on in the screen at a moment's glance. The player's ship especially should be a unique color that isn't anywhere else in-game to make it stand out. It wouldn't be a bad idea to do this with enemy projectiles as well. Enemies should stand out too, though it's not as vital as those first two, and player projectiles should be a much duller color than enemy projectiles, so the player doesn't get confused about which are his and which are the enemies.
