I think that a reticle could improve the feeling of the game, and maybe place the power meter beside it vertically, along with increasing the distance of the minimum power throw. I'd also change up the menu buttons a little. The other issue is that the yeti and penguin models clip when they dash, so perhaps a 3rd person camera would improve this. Most importantly, add instructions if you can. I didn't know that I had to hold LMB to get more power until like a minute in. I do think the game feel is pretty good overall. Keep improving and you'll make something great someday.
Attached is an example of how to improve the menu buttons. I just used free fonts, images and the mouse to make this, and threw it together in 10 minutes.I feel that an example is best when trying to improve visuals.
