Thanks for the feedback!
Yeah, the slopes are definitely something that should be addressed but unfortunately we didn't really have the time to find a way to address it. Maybe we can fix it in a post-jam patch! For the charging thing we did leave it since it as far as we saw it seems to reduce the total bounces that could be done after firing it so we thought it could offer some sort of strategy? But maybe it looks like it's a bug so we could also take a look at it. Thanks so much for playing!
