Nice little game!
I like the AI companion, I think it is a surprisingly unique take on the theme, since most other games you have control over the AI in some way, by giving them directions. So this was a refreshing difference.
I'll assume the AI is actually just a replayed sequence of commands, rather than an actual AI. But It did seem to get stuck sometimes on the top & bottom long stretch.
Movement feels nice, although I think the jump is a bit heavy, especially when there are some precision moments of needing to land on singular blocks. I also would like if there were more movement options, since I am used to using space to jump, doing wall jumps with w is very hard for me.
I like how the game is essentially a metriodvania, getting powerups and going to places with said powerups. Would be cool to see more powerups, as well as being able to see places we can't go to yet, since that is part of the fun of those types of games is being able to recall "oh, I know where I can use this."
If this were expanded, there is a lot of depth with having a second AI player following along with you. Having more things that they can do other than pressing buttons along with you. Their dialogue was nice, but it was a bit slow, and the text itself was also very small.
I think that the buttons shouldn't have a collision, since it can be a bit jarring to be moved upward to stand on them.
Nice job!
