You are absolutely right that the movement could feel smoother and that clearer feedback on robot stuns along with more checkpoints would make the experience less frustrating. This has also been a common critique from testers, and I will be putting effort into improving these aspects with the ideas you and others have shared so that I can release an even better version of the game in the future.
It really means a lot that you played it all the way through and still had fun despite the rough edges. Thank you again for taking the time to share such thoughtful feedback.
