OVERALL FUN:
1. This is my personal preference, but I do not like random encounters. Have you considered putting inkblot enemies on the map? You're in narrow corridors, so you can't avoid them, but then if you need to backtrack, you can do so freely without fighting a ton. Just a thought. Not a huge deal, of course. And then they respawn if you leave and re-enter the map for those who want to grind a bit.
2. I think your game would benefit from a starting ability—just one.
3. I like how you have different inkblot artwork, but they all do the same thing. A basic attack. Have you considered giving some a special ability to switch up encounters and make them all feel less repetitive? Right now, it's pretty grindy basic attack-mashing combat. Hit, heal, hit, heal... repeat.
4. Even boss fights only have a basic attack with no special abilities... :-(
ART/GRAPHICS:
1. I think many people will dislike the artwork, but I loved it. It's different and very unique looking. Strangely, it reminds me of Little Big Planet and the stickers we find—very stylish artwork.
2. You used the same animation for Basic Attack & your first ability. Each new ability should have a different animation to make combat more flashy and exciting.
3. You should do animations for items and recovery, as well.
CONTROLS/UI:
1. I think a Victory Aftermath screen would be an excellent addition. You can find some free-to-use online.
2. Controls were easy to understand.
3. Your menu has a formation category... but you only control one person (Blueberry). I will say... I didn't beat Strawberry and quit after that... unless you eventually get companions. If not, you can turn that off.
SOUND/MUSIC:
1. The music was mildly unsettling, which I liked. All the strange SE added and creepy ambient audio mixed in. However, you should get a second track for the right side of the map. After a while, that same song loop got a bit repetitive.
2. A different song for each boss battle would be nice. Same map music, and then the same combat music. A few more songs could help quite a bit.
OVERALL FEEDBACK:
So, please don't take this wrong, but the game is a bit repetitive right now. You venture through maps, search chests, and find the same two items. Enemies have no variety or abilities; even the bosses are normal enemies with more HP and larger artwork. I think combat needs some work. It would be nice if we got some additional items from the chests... and we have an equipment option in the menu... yet we don't find any new weapons, armor, or accessories.
Also... maybe add in some lore/letters you can find along the way to Strawberry. Maybe torn-out diary pages written by Strawberry, etc. You can start to piece the story together before you encounter her. Explain this whole "Jam Girl" thing a bit more.
Have you considered puzzles, locked doors, switches you have to find, etc? Right now, it's a pretty straightforward game... walk, fight, chest walk, fight, chest, repeat.
I will say it's fun at first! And I think this game has potential. I just think you need to add in more variety to combat, maybe some puzzles, locked doors, and additional story/content along the way. I'm interested to see where this game goes, though!
