The bombs did not work for me in the last level.
When using keyboard, why let WASD and ILKJ rotate instead of going for cardinal directions? You may have a good reason for it, but it did not feel good to me, at least in the beginning.
Is there a simultaneous aspect to the golfing? From the levels I played, it did not appear that way. Will that change in later levels? Or are there no more simultaneous levels? Which is fine, though that begs the question whether you could instead just have the game be controlled with just WASD and QE, and then give players the ability to switch between characters, like you can switch between fairies in Poke ALL Toads. Will the balls shot from different characters be able to interact?
In the "hills" level, could the hills thematically be changed to some sort of abstract slider, or maybe a conveyor belt as in Factorio?
Will there be scoring of how many balls a player uses to win the levels?
Did you ever release Bearcycle on mobile?
I enjoyed playing the game, very brief though it was.
