bite sized tower defense.  would have liked a quick description on the towers and upgrades, though there were few enough that it wasn't a lasting problem.  could have used more waves and more difficult enemies, like another layer for the splitting slimes.  It felt like I was just getting some towers upgraded when it ended.  Also a next wave button is a must for any TD, though the music seemed to sync up with the wave spawning so maybe that was intentional?  It seemed like the music swelling as the later waves spawned, which upped the mood
