-Pressing up to shoot? is odd. Please add any sort of visual for the projectile/attack.
-Oh actually it's shot automatically like a VS like.
-After killing a boss, it looks like it respawns and falls from the sky, but dies in one hit.
-Blade balls are looking a little funky, I only have 4 while I bought like 7 upgrades. It is also 3 in a row then on more on the opposite side. I'd either expect a straight line of them or an equal spacing, not this.
-Movement seems too limited for the level? I'm stuck on the floor since I can't jump to the higher islands.
-Oh I guess I have to interact with the portal to go through it, though the first couple times I thought I just teleported to the top of the map, not a new one.
-Found a -8 hp crate, but I only have 8 HP, and it's letting me spam it to get infinite xp without losing anything.
Fought some more bosses but I guess that's it. It's been a long time since I played RoR, but I feel this prototype is lacking agency, if you don't plan on having abilities on cool down, then there needs to be some fun platforming or VS style powerups to switch it up or whatever. Keep up the good work.
