This was a wee blast! I always find it absolutely mind blowing to see people make things with Pico 8. There are a few things that I found limiting or frustrating, but I'm not sure if they can easily be avoided in Pico 8 with the limitations. Number 1 - would have liked for the controls to be shown in-game, rather than having to read them in the description, and Number 2 - would have loved to have been able to use A and D instead of the cursor keys.
Despite that, had a great wee time, figuring out the controls and trying to dodge as best I could. In the end I almost exclusively used both engines at once to go up, or no engines to slide back down.
Great stuff.
