It took me several hours but I finally managed to beat the game in normal mode, got ending 1/2.
The game is excellent. I love the soundtracks, controls, feedback, speed and all are perfect and it really delivers tons of great bullet patterns which is why we're here.
Immediately dying when touching a wall is brutal, it ruined me quite some runs when not paying attention, I'm trying to constantly remind to myself "don't forget about the walls ... don't forget about the walls ..." when playing. No mercy, I like that.
Now I'm looking at the screenshot and realise it's like a different game from what I've played, I'll probably try to deal with Hard mode some day, the game's worth it.
I enjoyed the game immensely, thanks for sharing.
