Nice game dude, enjoyed it. Only things that spring to mind for me. I think improving the respawn time would help and also make it so you can't control the player on the fade in after a respawn, that killed me a few times but that's probably mainly beacuse I am bad. Controls felt a little bit floaty to me and could do with a little more precision. Though if given more time I am sure that would have been sorted.
I enjoyed the game, the art style was nice and the sound track was good but not overbearing which is a positive to me. I had fun playing it and wanted to keep playing.
