"Mobile port?"

No, but there's a small chance post 1.0 if I have a change of heart (please don't ask me about it). Emulators apparently work fine, just be careful where you get them from. I'm interested in Linux/Mac ports.

"Will you release free updates for every version?"

I will on a sporadic schedule, up until what feels like enough. (probably 0.51). Subscriptions are only $3.50, and you have options with sites!

"Will you release a guide?"

The final free version will get a guide. In the meantime, here's some tips...

• To melt the icicles, you can use Fire Jet which is obtained while exploring the upper eastern part of the forest then dropping down.
• Milly and Shadow must be encountered during nighttime.
• There's a secret boss that spawns a doorway in the treetops, towards the east.
• There are a lot of technical things you can do in the game, experiment if it's too challenging! (equipment, stats, try comboing normal/special/magic attacks together) Also, check the extra options in the main menu!
