Spolous Route A Hard 1cc
If you like Gradius, you need to play this.
Once you get over the somewhat amateurish graphical style, you'll find an absolute love letter to Gradius that refines and improves the formula. The biggest change of course is no checkpoints, and no more Gradius syndrome! Much like Salamander, you just respawn and can pick up your options. Every weapon loadout also has a special button; in this case, it's a simple speedup, but other loadouts can lock their options in place and whatnot.
There's five routes to select, each one based on the different Gradius games with unlockable hard and hard+ variants. Hard mode doesn't just increase bullet count or enemy health either; there's whole new enemy placement, boss attacks, and new sections added to stages.
There's several weapon loadouts to start with and more to unlock as you rack up credits from playing. The one that I'm using feels like a very brute force playstyle; there isn't a ton of coverage (unless you use the "vartical" shot, but you need to be quite aggressive to make use of it), but it's missiles do tons of damage and you can upgrade your options to mimic the ship's weapon and missiles, which they don't typically do.
