This game is great! I finished it yesterday (with 69% completion) and thought it was super fun! This is definitely be in my top 5 for this metroidvania month. however, i do have a few criticisms.
1. the early game is incredibly slow, and the jumps are too difficult. A game is ALWAYS going to feel easier to the developer. the early game jump sections were incredibly tight, and the game doesn't ever feel that hard again with its jumps.
2. the world is actually quite large! however this comes with downsides. the fact that you Always re-spawn in the same location means that getting to the edges of the map takes ages, especially when you have to keep going there (such as for the ability in the top left, or the final boss)
3. the final boss actually feels really good to fight, but is very inconsistent in difficulty. the attack where it flies into the sky and shoots down upon you feels fundamentally unfair, as not only is it the hardest attack to dodge, it also does not leave the boss vulnerable in any way, leading to it feeling unfair. a small vulnerability either before or after the attack would be great.
4. due to the height and floatyness of the jump, combined with the slow movement speed, the early game feels slow. really, really slow. the speed at which you move is too slow for how high the jump is and the way that the character falls. this also leads to dying being more frustrating than it should be, as dying is a much larger punishment with low speed.
Great game however! i cant really say much about the art (i cant make art either) but this game was really fun!
