I like the pixel art, and I like how you added some actual replay value with the upgrades! Honestly this would be great as a mobile game. Well done!
Thank you for the glowing review! We plan on making a mobile port after the jam is over, plus we want to add even more upgrades and replay value.
Thank you very much for the feedback! As seth said we have plans to develop a mobile version, hope you like it when we release it :)
