Really cool idea! I had fun playing it! Great job!

Cool idea! I like the different kinds of blocks, spwaners and repulsers are both good. There's a bunch of stuff you could do with that if you took it forward. The random blocks add a good amount of challenge, but it could be good to have some cost associated with placing a block or have higher cooldowns after better blocks. As it is, I beat hard by just putting a couple of block spawners on the back few rows and then just spamming blocks in front of them whenever they were off cooldown. Very much enjoyed it though, nicely done!

Well done. A lot of games in the jam attempted enemy or obstacle placement systems to reverse common game types.

This is the cleanest implementation of that idea I've seen so far.

Good job!

Great concept. 

It's hard to keep tracking where is the best place to put every block, but after a while I realize some strategies. 

Congrats for the solid entry! =)

A very simple concept neatly done and developed. I enjoyed every second of it, quite a challenge at the beginning but very fun and engaging. I didn't want to stop playing, even though the mechanics are simple I really enjoyed coming up with a strategy to win. Nice twist!

This was a fun one! The random blocks does make strategizing feel a bit haphazard at first, but I think it ultimately works well enough once the player learns to pay attention to the up next indicator.
