This was a fun little game! I really enjoyed it! The art is quite low quality and there is some weirdness is places but i don't think it takes from the fun. I'm not sure if there is a level two but it didnt look like it to me? Also i don't think health was implimented, but maybe that was planned for level 2.
The tetris minigames were fun, but could have used quite a bit of polish. 
The resource gathering minigame was gun, but i feel like the way attacks were designed encourages machine-gun-clicking. Which isnt really a problem but strikes me as unintentional.

Overall i really enjoyed this one, despite the low-quality art and lack of polish, it offered some fun mechanics and i had a good time.
