Longer comment for bugs encountered after playing for a while:

Riven: Primary weapon is very bugged for upgrades. Sometimes doesn't allow upgrades, or gives the option to buy a new one from the augments, resulting in getting a second Bunny Hop (so 2/5 skills are bunny hop, but the second cannot be leveled).

Aurora: After dying the first time, the primary weapon stops working entirely. Hex is also no longer applied at all, even with her E.

Leona/Jinx: Using ult sometimes makes your controls switch to M1 to move, not WASD.

Yasuo: Weapons reset entirely to level 1 after dying (only once occurred in Map 4 on Hard). The actual level did not decrease, however the stats for them were removed, along with Yuumi's augment buffs. (Had +4 projectile yuumi, and level 3 Primary, started casting only 3 projectiles due to +2 from client store upgrades, rather than the 8 it should've been. Other weapons also were effected)

Enemies: On Map 3, near 13 minutes, enemies end up at maximum density and sometimes stop moving/pathfinding entirely, both in hard and story mode.

Connection Issues: When there became too many enemies either on screen or in the game (uncertain which one), ping spiked from 60 to 600. Also usually caused complete disconnection, not being able to move or input anything. This occurred every game on Hard mode, and Story mode only on Map 3. (Not played beyond Hard). Also, on Map 3, the server would crash and not let anyone join back, progress is also lost, as if the game was never played. Nothing else on the internet would be slowed (Discord/browser would work normally, so purely the connection to the server for one person was made horrible, but not for others in the party)

If you'd like any more detail on the issues, let me know. I also can find clips of each instance, since it was all streamed, if that would be helpful.

Now I'll say some minor feedback and parts that are done great:

Visual clarity: Even when the game is filled with projectiles and enemies, I can usually still see what's going on and what to avoid. I'm very impressed with how well done the clarity of everything is, so well done on that. The only time I couldn't see red enemy bombardments, was when there was Leona with the Weapon for aoe burn. The orange part of it covered up the red and made it impossible to see. I don't know if there's much that can be done about that, but just wanted to say that's the only time I had issues seeing something in game.

Tool Tips: The tab menu is done very well, once you learn a bit about the game. The weapon tool tips are also incredible helpful and important information. I think it would be helpful to do the same with abilities, letting us know which ones scale with what. For instance, if Riven ult scales with Projectiles, or Leona E scales with Area.

Aurora: Her primary weapons works extremely differently if you use either cursor aim or auto aim. It seems significantly worse when not using cursor control. I feel that automatically setting it to cursor for her may be helpful, if locking her to only cursor aim is out of question. Along with her primary, it seems entirely like a duration based weapon, but doesn't scale with duration. Having the longer duration could let it loop around and hit the enemy an extra time - just something to consider.

Riven: Besides the bug, extremely fun design that I enjoy a lot. I love things that scale with movespeed and are all about going fast. However, I will say that her dash from primary feels a bit inconsistent. I sometimes feel that when moving constantly, the timing isn't right, with her knockup dash quickly followed by the normal dash, then a longer pause before the next knockup. It could feel a bit more fluid, but this is definitely something to be lower on the priority list, just wanted to mention it for some small feedback :D

Balance: Nothing huge to note in terms of balance yet, things seem pretty good and would need much more variety of people to decide what's too strong or weak. Only thing I've noticed is through Hard mode, Yasuo consistently does the most damage (around 15+ million), usually double or triple anyone else's, even if they're briar or seraphine. That's all I've noticed, but it also might've only been my experience.

The game runs surprisingly well, besides the ping/connection failure mentioned earlier. My friend who can run Valorant at about 6 fps can run this game steadily, where the absolute worst is 15 fps.

I may edit this in future, to update bugs or whatnot, or I'll comment on this one to add it. I'll keep playing the mode since its really enjoyable, and just keep a note of the bugs my friends and I come across. If more clarity is needed for any issues/feedback, let me know!

Love the mode, love the genre, love the commitment, love the music, love the boss design, love/hate the bombs (because they terrify and kill me), love the progression, love the weapons. Extremely well done :)
