Definitely will say I wish you had more time to work on this!
The idea is really good and clever. With the things work right now, I can’t say for sure how good this can be when it fully comes to fruition.
For feedback, I will say do definitely have something that can indicate when to catch the boomerang. I also found out you can hold the grab key when it comes, and immediately abort the jump as soon as you catch it. Holding F is also awkward if you aim with the mouse. Why not just use LMB trigger aim if you’re throwing anyway? It’s not like you have to literally throw in where the cursor is when the throwing guide is there..
I love the idea and hope you can get this to a proper playable state, bud!
