I saw some YouTube videos on it and it looked fun so I gave it a go. Enjoyed it immensely - easy to recommend even in its early form.

I liked building planes of various designs, from early wooden planes to light jet planes to massive cargo carriers that always struggled to take off.
I liked the simple tasks of delivering cargo from A to B.
I liked the progression of using the scrap from rewards to research new parts and experiment all over again.
I liked how it taught me the basics of aviation - even if the physics needs work.

I liked being able to the landscape as a ramp to help me take off. Fricton? What's that? Wheels? Who needs 'em? Trees in the way? They're bouncy and let me do sick mid-air cartwheels!
At one point I even discovered how to turn into a car to get the heavy cargo shifted over.

I didn't like the timed quests. I'm not against having time quests, but giving 30 seconds to not only get from A to B but also land safely otherwise breaking the expiring item and having to repeat all over again... way too restrictive. I ended up making a rocket to complete them and depending on parachutes to just barely survive the impact.
I didn't like the feeling of financial constraints when trying to build bigger planes to shift the heavier cargo. I just couldn't afford more engines so I had to compromise in other areas to scrape by.

Overall, the game in its current form is very enjoyable and I look forward to coming back to more content, balance fixes, and Quality of Life improvements.

The game looks like it would be fun, however I'm stuck at a point where it constantly crashes within a few minutes of trying to hunt anything, and nothing I try from reading forums seems to help. I guess I'll just sit on it a while longer and see if any patches ever get released to improve the stability.

A peaceful swimming exploration experience with a great soundtrack to go with it. I really enjoyed it!

Mind bending puzzles and an atmosphere similar to Portal and maybe The Stanley Parable, where the maze reconstructs itself around you. Only without any narrative voice to keep you company. I love it.
