I liked it! The Hybrid tower defence shmup aspects work very well together. The assets used are very cute, I especially like the enemies. Whom I have dubbed Purple Guy, Pinky and Shrek respectively. The gameplay loop works very well, and I like the emphasis on building up and performing well.
I do have a few problems and nitpicks though. Pinky dominates, Purple guy is hardly a threat and Shrek is only a threat because he turns into a Pinky, makes you wonder why the other guys are even there XD. I also feel like the enemies should be able to damage your ship, it feels wierd that they can hurt your defenses but not you.
Also the Balancing is whack, Half of playing well is rerolling until you get the busted 14 for two blocks, one a turret, and flooding the top of your defenses with it. Murders most of the waves. Wave 21 is also a huge shock to the system, since a setup that defends 20 well just crumples to 21.
On the whole, I enjoyed the 20-25 or so minutes I dedicated to the game a lot, and will be reviewing it well :)
