Finished my first run.

Boss 1 P3 still arguably and objectively unfair.

Boss 2 frustrating but reasonable. Particle overlap issues making it cheap dying to something you can’t see.

Final boss is very fun. Almost everything can be read by the player. Few scenarios where it’s a guaranteed death.

I saw how the firing patterns and enemies increases in difficulty after the boss but there was no frustration as you could enter a room and learn the patterns with no consequences.
The boss I’m arguing even with learning the patterns creates an unfair advantage with its speed that is not fun (P3).

To my friends I said I’m “not enjoying this hide behind pillar simulator”.

P2 was great. No need to hide all the time as the patterns were a good speed and shape to jump, slow dodge etc. P3 ruins that by getting hit by pure speed of the bosses firing rate. The patterns trap you

I did learn all the patterns. Made it to the end of P3 multiple times no issues. Would still argue that he fires his patterns faster than reasonable in P3 to be considered fair. It didn’t feel good to defeat him, I just smashed my head at him enough times.

Enjoying the game so far! Unforgiving but captivating.

Quick feedback: phase 3 of the first boss is rather unfair to the player.

The player has no way to combat the speed, strength or damage of the boss often leading to rage instead of fun.
Phase 2 I would argue is the fun part of the boss.
