First of all i have to say that, i really loved the theme of the game. I have always been a sucker for air pirates and islands on the sky tropes in video games. I liked the graphics of the game. It has a good classic roguelikey feeling to it. It has good color contrast. Graphics does a good job for reflecting the intended theme of the game. I like the UI and HUD , they look barebones but i don't care about that in a jam game, they diplay the useful information to players. I liked that the player and enemy animation is lerped. Controls feel smooth. I like ranged combat but the starting revolver misses too often. The highlight effect which shows the gun's range is well executed. There is sneaking in the game i but i don't know how it works. I didn't see any stealth stat anywhere. I like the enemy aggro system and how it's shown with exclamation points. Pursuing enemies is a good mechanic to add tension to the game. Allies is a good mechanic, you can switch between multiple characters. You can restore a part of your HP but i think the game needs some healing items i think it's one of the reaons it's too hard to progress in the game.
I think i played more or less 10 runs in the game. When you activate the ship travel screen, there is a text saying Sky Islands 1/5 so does the game end when you pass the 5th island ? Or does the game has no ending and that's why you say it's incomplete. But in any case i honestly think that it's a playable game with solid ideas and a great premise. I don't see a failure here at all.
Thanks for your submission and good luck on your future games!
PS: There is a bug in the game which you see when you get an ally. The UI switches to ally's inventory but the inventory data is still the primary character's. When you switch to ally character in the ship, it's fixed. I think it only happens when you first get an ally
