I just played the new version. Here is my take:
- Enemy placement is terrible:
Like this one
You already have to dodge a lot of meteorites, making this enemy even more impossible to handle.
Some enemy spawn points are located right next to each other, so if you need to move back to dodge the enemy projectiles while caught between two spawns, they just keep spawning repeatedly.
And sometimes you put too many enemies in 1 place, like too much.
- Almost all bosses are hard—not challenging hard, just nearly impossible, like Reactor Man. If you try to dodge under him, the projectiles fall right behind, making the dodging area so small that you need to execute it perfectly to avoid damage. I believe Glacier Man is a well-designed boss. You should create a boss that gives players a chance to dodge without requiring them to take the heart tank to push through it.
This is just my opinion on some flaws in the game.
