Super fun and very polished for a jam game! You could do a lot with this concept.

It might get tiresome running around collecting the crystals, but it's clever design; It makes you decide between moving the tower and earning money for upgrades. Also gives you something to do when you don't need to move the tower.

Stunning art and a really clever concept too! Great job.

Absolutely loved this! Really unique and super fun!

Wow this is probably one of the top 10 of the entire game jam! Good job!

I enjoyed every single level even the credits screen :b

Hey, we made a GMTK game too. Check it out!

Very smooth gameplay here !  Good job !

Cool game! I specially liked the boss and the ending was an awesome little touch. There is one thing that I don't know if it's intendeed, when you are carrying the tower you move way faster.

absolutely brilliant, I loved this game, and admire your work, humour and mechanics. So original and wonderful!

You know, after a while I actually forgot this was a jam game, it's so nice and polished! Congratulations! I think you'll make it to the top :)

This game is a really cool concept. I really enjoyed frantically running around to place my tower to keep the enemies at bay. Only critique is that the rules were not obvious to me. Took me till wave 4 on the first level that I realized I needed to pickup the crystal things to upgrade my turret. Other than that this was super enjoyable to play. Well done!

I didn't think a one-turret tower defense could work, but this is absolutely fantastic, feels great to play, nice feedback for each shots, adorable art and weapon upgrade (I think the selection cursor should be made more visible, a small red triangle is easily missed). This game has the potential to become a truly deep tower defense (adding more turrets, various shots and whatnot!). Really good work!

Amazing game, art and gameplay are perfect.  Congrats to the team!

Please, add more levels.

Great game! Great Art! Great execution, I hope they continue this game! 

The art, theme and execution are flawless! I hope you continue to work on the project, it deserves more stages and upgrades. 
Also love the sense of humor, let me pile on the hats, hat only run is the true meta.

As other said, awesome game ! Really love the attention to detail and the overall feel of the game. (PS: I would have loved other controls like arrow keys for non-qwerty keyboard layout)

Honestly probably the best game I've played from this jam so far (of about 20, but still).  I really liked the tower defense idea, since it's a genre of game that I wouldn't think would work with only one tower at all (at least more than trivially), but you made it work, and fully thought out the idea.  The gems keep the player engaged too, so they're not just waiting while the tower does its thing.  I'm super impressed too that you managed to have a boss stage as well.  And of course the art is really good.

This game is awesome, really polished and well made with good enemies and flow. I'm pretty sure i ran into one bug where the speed power up seemed to carry over between levels when you pick up the tower but honestly it's not even that much of a problem.

Amazing idea, super polished execution, an awesome game!! Really really great job. Such a great concept, fits the theme perfectly.. Great job! my best rates!

probably the most polished thing i have played in this jam so far. love everything about this.

Really great execution of the idea.  The art is great and the controls are slick.  I really liked how you guys added the gems to collect which keeps things interesting for the player.  This has always been a negative of tower defense games.  Awesome work!

honestly I gave this one full marks. We thought about a 1 tower tower defense but this take on it is just epic IMHO. Good job, well flushed out, fun graphics, effective sound, solid adherence to theme.
