This game is pretty clever. I like it, but it would be nice to have some reloading feedback and the cannon could have more health. Otherwise whole game is on point. Good job!

This was a pretty fun tower defense game here. Them music fit well with it too, but I would of loved it if the cannons cooldown shot was lower or I could get a powerup so I can shoot faster. Overall, nice entry!

Game looks good and plays well. As the others mentioned, it gets challenging very quickly, but with the limited time in the jam, there isn't much time to spend on balancing, In any case the most important thing is to get the game out there. 

This is great! Feels polished for only a few hours. Might be cool to allow some means of repairing/rebuilding towers if you continue to develop this game. Either way awesome job!

Gameplay loop is hard because the more you lose canons, more likely your are from loosing others. Congrats nevertheless !
