I'm so sure I had posted a comment about this, but now when I'm returning I see I may have left the page to early or something. But it's not possible to leave this game uncommented.
I LOVE this. It's by far the best TD game I've seen in a jam-setting. Insanely well done, from the mechanics to the art everything is simply solid.
I am a sucker for TD games in general so I usually have very (perhaps unfair) high demands when playing one. That's an issue I have to work on, especially when playing jam games ;) - but playing this I realise I can keep my high demands because you've shown it's nothing but possible.
The only "bad" thing I have to say about this, is the weird crash that happened often enough to cause a problem with playing the game properly. I struggled to find some sort of pattern but I didn't manage to find much. But in many cases, when a mob got all the way through and dealt damage to the base, the game would simply freeze. This seemed to happen only for the first time damage was dealt. As soon as you took damage and the game didn't freeze, you could relax knowing it would not happen again that level.
Sadly, this could happen on level 3 and then you had to reset the game to start over and hope it wouldn't happen again, but it did a lot - sometimes on the first, sometimes on the second.
Also, when I managed to clear the first levels I had the options "try again" and "main menu". I didn't want to try again, because I wanted to move on to the other areas (couldn't get enough of the game :D) so I assumed "main menu" was the way to go. But then I noticed I hadn't unlocked anything else. I tried to then go back to the first, clear it again to see if I was supposed to press "try again" but then it crashed for me on level 3. :(
Is it possible to unlock other areas or are those teasers that are not included in the jam version? :)
And, to complete this fine compliment sandwich - this game is simply a gem and I hope to see a fix for the issue because I really want to keep playing.
Thank you for this game! <3
