Great game! The visuals are very good in my opinion, also de sound design... The inputs are a little clunky though.
With that fixed, I would add a few more enemy types and levels, and it would become an awesome indie :)
Thank you very much for your comment, we updated the game just a few minutes ago, if you want to test it in better conditions ^^
It surely feels like a completely different game with the update... Congrats :)
