Good game!
I love how you introduce teh different mechnic to the player using classical internationnal notation. Difficulty is very progressive, I wish it was a bit longer ! but it’s really polish. I would’ve love to see more interaction with the bot (maybe he too can activate thing on our side ? because otherwise it look like it’s just a well made timer. Having the spikes came out again could be a cool way to make sure the player doesn’t take to much of a lead, but it would need to be more explicit. A good way to do that is using sound ! A big loud sound when it extend and a another different one when it retract. Overall, I like the level design. I do think the player is a bit too slow tho, maybe having a sprint button could be a good idea
GG!
