Generally I don't have the courage to leave reviews, but I think this'll be my first one.
To be honest? I think I like this Amy better than what base SRB2 has! She's more fun to play in a general sense without being a hard mode that I feel didn't suit her by comparison.
I do, however, have 2 nitpicks that I have and wonder if you can address them:
1) When using the hammer, I'm not entirely sure if her hitbox becomes bigger or not? It's not a game changer but I wonder if that could be considered so that it does become bigger?
2) Sprite-wise I noticed that the hammer movements are just taking her base-game hammer sprites and putting them on loop. Spriting is hard and tedious so I can understand why this was done, but I feel that's something to possibly look forward to: having unique sprites to fit the actual actions in the future.
Reminder that these are just nitpicks! Aside from these, I'm much more comfortable and excited to play this version of Amy, so thanks and good job on this!
