This has the workings of a pretty good game but it's missing a lot, some of which are the most basic of things for any games.
Basic functions like Mute and Pause are seemingly absent
If they are there I have no idea because there is no explanation of anything. I hit every button trying to figure out anything. I also have no idea about what speed does, what each powerup does or what is even a powerup (my first run I tried to collect an enemy because it was yellow, solid, not moving and looked like what a typical powerup might look like).
Game play is confusing too. It might seem simple but it's hard to tell the difference between a survival based game like this (I think) and a retro arcade style shooter without any explanation such as controls.
The hitboxes seem off, especially when turning. I think they expand to a box from top corner to bottom opposite corner which causes a few deaths.
I'd be willing to give this a much better review because as I said, it seems like it could be pretty good, but there is just so much lacking here. Good luck.
