Onward

Onward is a tower defense game but instead of defending an area, you are continuously moving forward to different levels to attack the attackers! After each level you move onward to the next! Each level gets harder and harder! There's also a resource tree that lets you prepare for you trips by either giving you items to upgrade your minions or by directly upgrading your minions before you set out! Take over an area with your minions! The only limit is the space available around you! Place minions to attack for you! Upgrade them to have them do more damage and get special abilities! Prepare for your journey by upgrading! You're able to upgrade your minions directly from a resource tree! Upgrade more tiles to unlock more minions and even more tiles! You need to keep going... You need to continue onward...
