Currently my favorite game I've played this year, up to my fifth playthrough as of writing.
I've really been enjoying taking different characters through this and relearning the levels; I'm still finding a lot of little surprises everywhere (like hidden Hee Hees that put a smile on my face). The art and music are excellent and I see and hear a lot of love everywhere I look and listen. You listed the modtracker artists you curated from, would you be able to list the songs used at some point?
My only solid complaint is the final boss.
The final boss is a bit of a difficulty spike and isn't a very dynamic fight- I've had varying success with different characters but what usually happens is I hide behind the goblet platform, wait to remove it, and find an entry point on the boss. The horde of matryoshka dolls can close in quickly while the boss is preparing a hitscan, and with few other places to hide it's quite easy to lose the five rings given for the fight for good if things go wrong; and the conditions and arena layout are quite intense to make it through with no rings. I've also had the boss' attack straight up ignore walls I'm hiding behind on some playthroughs. A better balanced final fight is all I'd need to give this five stars.
On a separate note, is it possible to get a Super form for this pack? I've only found two emerald tokens, and while I need seven there are only five levels. I'm still relatively new to SRB2, can I replay levels and get the same tokens again to get new emeralds? I'd love to explore this with a Super character.
Very much looking forward to Zodiac whenever 2.3 comes out.
