Several things...
1. Some spelling errors. "Poison" is misspelled just about everywhere I look. Please fix that...
2. The music and sounds part could use some improvement. Battle music could use some variation in my opinion.
3. I encountered some sort of "bug". If 2 / 3 of the party members die and the last one standing was made to use a healing item other than a energy capsule on one of the dead members, they use it on the already dead member and it "restores" their hp.
4. Healing and damage to enemies is ridiculously high after some point.
5. I counted 12 achievements.
6. Healing with Axl seems to charge everyones limit if he uses a party heal.
7. Bosses and enemies are somewhat too easy. The hidden boss was not that hard to defeat.
8. Controls could be user defined.
9. One thing I found really annoying: having to hit the space bar twice to confirm an attack on an enemy, though I can see where you are going with this.
Looking forward to the next chapter, whenever that may be.
