Fun for what it is, and hard to complain about a surprise free release like this, but it does start to show its problems on Furier mode. Some bullet patterns are very annoying to dodge because of the invisible walls, the contextual shoot/melee button really does not work well, and parry being back+attack rather than a dedicated input is annoying. Lot of things are just unclear generally, unsurprisingly not as good as the full game. Worth a quick playthrough on the base difficulty then put it down imo.
