The only thing I had problems with was rng, it really hated me. Like for real, my first playthrough it took maybe 1 - 2 minutes until I got a new pair of greens. I got a destroyer at some point though, just enough to destroy a few reds with it and keep me alive for a bit longer :-D It was like that for a while until I game over. My second playthrough I got a good amount of greens, but then rng started to hate me again :-)
I've had experience with the game before, so I've developed some mad skills at this game, and rng has grown to hate me.
Personally I think the gameplay is fun and interesting for a little while, and with more juice it can be more exciting. But as I said before I believe that is because I have prior experience with the game, so I'm not confused like I was the first time I played it. But at least there's instructions now to help newcomers learning the game a bit easier :-)
Anyways, well done on the game and that you got to submitting it :-)
