First stage took me three tries; second and third stage took me no retries, fourth stage took me ~4 retries I think. But I finally did it. Really took a while to get used to the control and the hitbox.
First, the good parts:
The graphics are top notch, especially the background. It's apparent the amount of effort put into this game.
The boss designs are awesome. Putting ominous overpowering boss right at the start -- love it.
The theme interpretation is pretty creative -- and I like the story with the ancient sanctuary.
And the music -- as expected. Esp. the one for the last boss is epic.
Kinda hard to believe you started somewhat late.
I can't overlook, however, the issues I had with this game:
- The movement control... is the biggest complain I have with this game. It's way too slippery; and since it seems you are indeed somewhat aiming for a bullet hell with the amount of bullets there, in my opinion slippery control like this is a big no. Can't squeeze through tight gaps with this control y'know... which imo is one of the main funs of playing bullet hell games XD
- Also... I have got a feeling there are some issues with the arrow keys control input. I found the WSAD control to be much more responsive; the arrow keys seem to sometimes fail to let me move diagonally.
- I think it'd be more fun if the shooting attacks is a little bit more powerful... or at least give an illusion that it's more powerful than it looks -- for example by making the shot rate (much) faster, adding some enemies that are easily mowed, etc.
- Minor issue: The wave attack. Since its bullets go up and down I don't think wave bullets should be deleted when going off screen vertically
- Idk... but personally I find it just a liiittle bit annoying when a gigantic boss with gigantic area of denial can only be damaged in one specific spot with tiny hitbox :P. Just a suggestion: how about if you make the boss be able to be damaged anywhere but gets more damage when hit at the weak spot(s)?
Overall still a good game. Keep up the good work!
