I did, yes. It didn't do too much, to be honest. If you continue developing, I think the places where your focus would be best spent are:
- getting the ship movement feeling as smooth and controlled as possible.
- level timings, by this I mean that the optimal line through the level should be available. For example in the second blue level there is no way to get trough the first obstacle cycle without slowing down( at least I couldn't) and that felt bad. I restarted maybe 50 times, getting the line as clean as I could but the time window was off.
