This game was impressive!
Your idea was very unique. There's a lot of work and effort put on this game and it's noticeable in the art, the building of the maps and the details of the gameplay. I admire that you built a tutorial, a really complete menu and multiple levels. I can't imagine how you reached that in only three days.
I was not able to finish the first level, there were a lot of enemies, they all had tons of HP and they damaged me too much. You created a really hard game, but even hard games must have some rewards to increse the motivation of the players to complete them.
I think the way you applied the limitation could be better, it's not something that actually modify or define the gameplay, it's more like something additional.
Even with some aspects to be polished, this is a great work and I have to give you congratulations for finishing something this big for a three day jam. Keep doing games with this level of quality and eventually you'll create a masterpiece.
