I really liked this game. Especially the first few levels. I have to say I really really don't like the things that give you negative time. Losing time because I see no other way to progress is just not fun.
The biggest thing that this game is missing is a bar/circle/whatever that shows when you will be able to do the thrust thing again. I'm sure you get used to the timing, but its very annoying when you want to do the thing, but you were early by like 0.2 seconds.
I also tried speedrunning the first few levels, which was pretty fun! And I also beat the first level without any left clicks for some reason. No idea why I did that but that was also pretty fun.
Again. I just need an indication on when can I thrust, and when can I not.
