If you enjoyed TSWoAR please check out the remixed version called:

Infinite Tower of Wizard Power

http://gamejolt.com/games/infinite-tower-of-wizard-power/127983
Infinite Tower uses TSWoAR as a jumping off point and adds a leveling system and a much more exciting difficulty curve that slows increases the size and health of your enemies instead of simply flooding the screen with them. There are also special powerups from defeating a boss wave, new weapon types, and no longer any need to hold down the fire button!

This is an early build. GameJolt API and other features to come.
