Hey there! I gave Last Infestation a shot and I genuinely enjoyed my experience!

Here are some things you did phenomenal on, and some things that you can always change to your liking:

Things done very well:

• The difficulty of the game is set just right. The player isn't expected to last for all of eternity unless they are genuinely the GOAT at games. The difficulty spikes feel just right. It's always a delight to have more testers help you out, but I'm just one guy giving you props on this one :)
• Controls are smooth for me. Simple, and effective, and it's not a hassle for players.
• Sound effects that you added or modified sound lovely. Sound is a huge factor in games and it's not often spoken about in feedback, but it's something I would also like to highlight. It's also an important note for any project that sounds shouldn't be overly obnoxious, but Last Infestation is sounding great!

Things that can always use a small tweak:

• New art was added and I know sometimes a game TOO simple looking might turn off a player, but sometimes, simple is good. Maybe adding a few more clear environmental items would make the game a little more aesthetically pleasing, but what was added is perfectly fine, but it doesn't hurt to add a little more (to your liking of course). 
• If you want to introduce more enemy types, that would be awesome.
