Glad to see it got an update! Are you planning for a full release eventually?
I'm really not sure! I have some ideas for what the final version might look like, it's not too different from this gameplay-wise but needs a lot more work on the audio and visuals, dunno when I'll next find time for it.
I did improve the controls a bit since the latest release, should probably get that out the door soon at least (and publish a changelog which I neglected to do so far) x)
