1.00.4 Glitch report:
all here was done in Hunter difficulty
Hadoken: at Axolotl stage, the sliding bar enemy, when hit with a fireball with its dome still on, freezes into default state and enter invinvibility, setting a softlock. I've had some other enemies display similar behaviour, but I'm drawing a blank about which and where. Dumboy Mikey had the same with Vile Armor in Fortress1
Fortress1 boss: as many have reported, one wrong crush and you're invinvible and noclipped. It's still possible to win the fight if one bounces and jumps like a madman, wallkicking at the pistons and tap-jumping on them. By defeating the boss, you'll be dropped OOB, but the stage ends normally (tested on my 1st run)
Ride Armors: sometimes holding up and jumping lets you out of them (MMX1 behaviour, the good stuff) . sometimes you need to do the simultaneous up+jump
Sometimes being too quick on pressing Start to skip the boss conversation leads to a softlock where the conversation over flag never gets set
1.00.4 peeves:
Beam is effectively a 2-hit long shot. nice against normal enemies, nearly useless against bosses, as it does less damage than LV2. Less DPS than using LV2 charge and ends up forcing the player to time the charge as not to reach LV3.
Special weapon charged version either eats too much ammo, or eats nothing at all. function is also not much clear (laser charge is a nice reflector, but where it would be usefull, like Fortress2 Boss, it lacks)
Special weapons are mostly good, but they barely reflect the bosses and their attacks (laser, gust and boulder being the clearer connected to the maverick)
Hunter Mode has some crazy difficulty swing. Some bosses are easy NoD runs, others are simply a tanking damage festival (Monkey, Axolotl, Fortress 2, Beard Sigma)
