This game is Neat ;)
- It feels very fleshed out with lots of content; your 2 years of work definitely shows in the game
- Beautiful graphics with soothing color schemes
- Fun bosses with interesting mechanics
- Interesting world that makes me want to keep exploring
- The difficulty feels good (coming from someone who doesn't play metroidvania's mind you)
A couple humble suggestions:
- Remappable buttons (I used an Xbox controller and it felt unconventional to press Y for interact and B for melee)
- Ability to re-initiate dialog (in case you forgot what the NPC said)
- The beetle is a cool enemy; it would add a little interest if it could only be damaged from the rear since its face looks pretty tough and armored
- The graphics are beautiful; I understand the aesthetic you're going for, but perhaps adding more contrast to a small number of elements may help it pop out in the screenshots (this is assuming you're going for a commercial release)
- A quality of life feature would be to have the interaction button hints match your current control scheme (when I play with gamepad the hints are for the keyboard keys). I saw a tutorial on this the other day:
