Hmm... It seems broken. Something to do with the resolution, the other comments mention it too. I couldn't ALT+ENTER (or any other way to window the game). A bummer because this looks to have solid gameplay attached to it.

I think this could be fun but as others have stated, I can only shoot away from the planets because of my resolution.

Setting screen resolution to 1280x720 made it playable for me.

I enjoyed it. The visuals are fun and there's interesting mechanics. I found it very hard to get any upgrades when each level you lose 6000 credits. The "hold left click to charge" upgrade felt very underwhelming, i prefered playing without it :D

Cool game!

I would really like to play this game, but in current state it's completely broken. I think this is somehow connected with the resolution of my monitor (2560 x 1440)

I really don't know how to play this when I can only shoot myself away from the planets. I like the concept though!
