I liked the game a lot! The concept is amazing, i always liked to spin chair like that so thats like THE PERFECT SIMULATOR. I DIDNT KNOW I NEEDED IT BUT THANKS FOR MAKING IT. And i looking foward to the updates.
Now regarding the gameplay itself i liked the gameplay loop a lot more than i thought i would, you were able to make a pretty engaging and addictive game! I could play it for hours (or until my hand fucking dies). So i think you are in a pretty good direction in general.
Some minnor things i didnt like was only that the way the game works isnt intuitive sometimes (like the fact that the rocks makes you faster, how the boost in the beggining works, how the money works and what triggers the chair to go up). But these are minnor things that the player can figure out in some time so i is not that big of a deal.

I guess the major problem with the gameplay is the balancing of upgrades that makes the game feel a little grind after some time, but i think you already knew that so, the others aspects are great so far.

Another major thing that i didnt like was the flying chair section, i think that trying to catch the rocks is a little too dificult, and relies much more on luck than ability since the controls at that part are too clumsy and the rocks are too fast... That makes that part very frustranting to me after some time (but take this with a grain of salt, my reflexes arent the greatests so maybe i just suck at that section hahaha)

Promises made, promises kept. We all want to be able to spin a chair like this! Amazing time killer!!! I would get the high score to actually accept input though. Going to make a tornado in that room now!!

I like the concept you have for this game! However, my arms and wrists get tired very quickly from doing repetitive motions so I was not able to get too far into the game. I wonder if it would be possible to add some alternative controls like pressing two keys (i.e. a and d or right arrow and left arrow) or going left and right on the analogic stick of a controller for better accessibility?

I do like the idea of farming money by spinning the chair and getting upgrades, very addicting!

Whee! This one was a lot of fun.

I think the core gameplay loop you have here works very well. The two phases of gameplay are pretty different, so that keeps things interesting, and I think the short duration fo each loop keeps things moving too. I did find the chair a little difficult to control after the space launch, since it doesn't follow the mouse directly - maybe having an upgrade path to improve the tracking could be interesting? I think having some more sound effects for destroying objects would be nice too, to improve the variety.

The graphics are basically perfect, I think. Bright colours and low-poly 3D works very well for the genre.

Are you planning to make a mobile version? I think this could work very well on a touchscreen, since the controls are fairly simple, and I could see myself playing this while waiting for the bus.

I'll leave some feedback over on the Google Forms link too.

I have enjoyed playing it!  Next day closer to space... Thanks for this great game!

At first I was thinking: okay,  it would be a fast playtest...
After 1 hour ... still playing XD

Gameplay is great! Options to buy upgrades is working very cool! Flying into space has encouraged me to play further!

Very nice low-poly graphics and sounds!

A litlle bit of balancing -> and it will be perfect. Currently after level 5-6 on upgrades I can not see them to help me a lot anymore, and stucked somewhere around 300+ spins.

What I like most of the game is FUN -> Thanks for that!
EDIT:  have also leaved feedback on google forms

Just want to hijack this comment as a reminder: the version to play is a DOWNLOADABLE. So please scroll to the bottom of the game page and download ChairSpinningSimulator_vPlaytest.zip
