Very interesting! I like that you can't get upgrades for the color your currently using, so it encourages different strategies, and I like that different enemies encourage different colors. One bug I found was that after I died and tried to play again, the waves were all messed up. Nice :)

Cool idea, just kind of buggy with the wave counter and way too hard.

Really nice tower defense, it was so hard to keep up with all the enemies sawarming the field at once.It was a bit hard at first to balance between the different colored tiles. A problem that I noticed is that the more progress you make troughout the waves, the less you're incited to use regular tiles, since they are not fast enough to eliminate enough enemies to survive the next wave. Maybe increase their original speed a little, otherwise that's pretty much it. Also, if you lose a battle, return to the main menu and retry, the game won't spawn enemies anymore. Apart from that, nice job :)

Aside from the issues others have already mentioned, it is a great take on tower defenses.

Really cool idea. Shame its not working too well atm.

The waves don't reset, major bruh moment. smh.

Some Bugs noticed:
- Sometimes I didn't get money when killing creeps
- Sometimes I couldn't get the next wave (not appearing and button not working)

Some ideas:
- Reward player when letting the next wave come in early

You have a really cool concept there.
I quite like the idea of the different tiles.
I didn't first get it, as I had not read the tutorial,
but afterwards it was interesting.

For strategy I think there is a bit more room to explore.
Currently some tactics feel a bit unbalanced.

In general a pretty polished nice tower defence game.
