Deluxe kru!
The game is definitely tougher than I remember it but nothing a quick 10-15 restarts can't fix to get in the groove, I got 22bil and 17k items in stage 1 original, and triggered Tank Mania, cool that there's a "trick" achievement for each stage (except 5?), and like 146bil after dying on Heca.
Being able to use the old HUD graphics (blue stripey metal) owns, pleasant surprise there, just feels like it has a bit more personality.
Weird stuff:
How do you get replays from the online leaderboards? Maybe you can't but I figured you can since the game gave this impression that it'll have basically all the same features as the Ikaruga port (same price point, co-op but local only, all the ancillary stuff like steam trading cards)
Where do you see what those small achievement icons in the HUD mean? STATS doesn't tell me, and they don't seem tied to the Steam achievements.
Btw, if you got the OST, plug in and listen to Evil Miasma all the way to the end,

fav track for sure.
